i had that happen once before at a place around the block from my house…i didn’t realize it until the pump clicked and stopped pumping because i was full…and said i only owed like $X.XX…i was confused, realized the problem, went inside to tell them about it…and the clerk said “oh look at that…wow…well, have a nice day.” didn’t give a shit at all.
I’m not sure if people that just work the front desk at those places has control over the price…i wonder if sunoco or mobile has like a senior rep in areas with a password or something in charge of making sure all the prices are right…i dont see the company trusting some highschool kid with something like that
