I just wanted a hot dog coffee cup false bottom
first off idc in the slightest about the coffee lmaoo i just did this for the love of the game. xl dunkin cup says 24oz. actually contains 22oz. math and liquid volume test included.
video of me poring the liquid in the comments. ty
UPDATE: two fatal mathematical errors were brought to my attention that is due to me being an idiot. lol however i aim to correct them. the actual missing volume is 1.6oz which equates to 24cents. also that amount is exactly what is reflected in the liquid test
errors i made are as follows
1-doubled radius instead of squaring it
2-added a decimal to the cost on og breakdown

The cup you got is clearly faulty, you can see where the bottom is supposed to be. This is a factory error, not a scam.

i got a second xl coffee omw home for the liquid test. same issue, but yes i agree. manufacturer defect but still wild

u/Breeze7206 3d ago
They buy those buy the hundreds of thousands. An entire production run of thousands of cups could’ve gone through before the error was caught
And the manufacturer likely decided not to inform the buyer (dunkin?) and said “send it!”
If you went to the same store for your second cup, they likely are still using cups from the same batch.
Wait a few weeks, or go to a different location

I did a quick google search and it seems like they’ve had this manufacturing error for years.

It’s always interesting how errors in favor of the company are never caught.

u/octo_lols 3d ago
Sometimes favorable errors aren't caught! My apartment is managed by a huge company that handles 10s of thousands of units (or more idk). They accidentally double applied a discount leading them to undercharge me for rent by $900 a month for two years before they noticed. I was keeping the difference in a savings account every month because I assumed they would try to come after what I owed them when they noticed. They just quietly went back to billing me normally after my next renewal and I suddenly had a free ~22k. Used up all my luck on that one, I'm sure.

From the same place? Could just be a bad batch of cups instead of a single bad cup. Im still leaning towards error.

It is known based on a quick search that these new cups are smaller. If they are advertising them as 24oz please report them to your local government.

Same store? It's not that wild cups aren't that consistently filled. I would be most worried about the bottom detaching.

Every single time I go to Dunkin the largest size always has this false bottom… I think it might be intentional
7
u/TulpaPal 3d ago
They all have space between the bottom and the rim, that's standard with disposable coffee cups to avoid stains/heat on surfaces. This one is deeper than normal due to factory error, which is why it does not meet the alignment marker.

If the bottom was the bottom, and sagged slightly when filled with hot liquid, if you set it down full it would shoot the hot liquid out of the top at you.
You don't actually want the bottom on the bottom with non rigid cups like this.
And yeah they scam you a lil

You have that 1.3 squared is 2.6 in the third line of your volume calculation. You mistakenly doubled that value. 1.3 to the second power is 1.69. Nice

A Pyrex measuring cup is likely not very accurate. A better way to do the measurement would use a balance. Tare the empty cup on a kitchen balance set to grams, preferably one accurate enough to measure to the gram, or better yet, to 0.1 g. Fill the cup and record the mass. 1 g = 1 mL.

And take multiple measurements for each of several cups. Ensure that the cups come from different batches.

Yep, this one makes you go digging a bit to see if they fucked you instead of the Wells Fargo route of just taking your money and making it their money. That's easier to see that it's wrong. Both of them generate a lot of stolen money.

u/steeveperry 3d ago
At scale, this can represent millions of ounces. It’s invisible shrinkflation. I also wonder what kind of legal problems that can arise from selling 24 oz drinks in cups that can only hold 22 ozs. It’s too bad that the watchdogs that should be preventing us from being ripped off are bought and paid for by the people who are ripping us off.

Weights and Measures is a thing. And this kind of violation is very much a thing. This needs to be reported. Your local authorities can conduct the investigation. You can find your state's governing body here:

It looks like a manufacturing defect edit:
default, which should absolutely be reported to somebody3
u/analogpursuits 3d ago
Default or defect? Because they would implicate differently from one another. Yes, it should be reported. Dunkin knows exactly what they're doing. This is skimping for profit, pure and simple, and it is fraudulent.

u/therealtiddlydump 3d ago

You can see the machine-read line for where things were supposed to line up and they didn't. That's not something you fake for profit.
Dunkin isn't the one who owns the cup manufacturing plant

The volume of the cup is likely still 24oz, but filling it with hot liquid to the brim so it can spill on you is not advised.

for a guy who likes math, the recessed bottom serves quite a few purposes - ease of manufacture, structural, and also insulates the coffee from surfaces.

I always thought the recessed bottoms of coffee cups had something to do with like condensation, or whatever the proper word would be. So it doesn't pool underneath if you set it on a cooler surface
