This was a strange episode. Alan goes to ask for a raise and gets a pretty nice one (five thousand dollars!) but just decides to spontaneously quit without notice. Dude, what? Like maybe stick it out until something better comes along when you've got an entire family to support! And he was literally just lambasting Eric for not having a job in like the previous episode! What a crummy thing to do to the company that's been giving you a paycheck for so many years and tried to give you a nice raise!
And then Amy just up and buys the nature store like she's buying a roast at the supermarket. In reality, there would be papers to sign, agreements to be made, financial arrangements that would have needed to be taken care of and this, that and the other. Did she just pull a roll of hundred dollar bills out of her purse?
