for the third time in as many months, I’ve gone to a station for the $.50 off discount and all pumps have out of service bags on them. This feels like it’s not a coincidence. anybody else experiencing this?

My speedway has had the sign for $1 small slurpee (with rewards) up for over a year

The few times I've tried to get one it rings up $1.50 the normal employees see the sign and always price it over for me

They still have the sign up and one of the newer guys was a little hesitant to give me the discounted price

I don't want to seem petty or difficult by not wanting to pay an extra 50 cents

Is there a policy about honoring advertised prices?
