Ok, so I take my hubby's car to work today and on the way home I stopped to fill the tank. ($34.00 for a 1/2 a tank)
Anyway, I fill it up and wait for my receipt and it reads Please See Cashier For Receipt.

If I wanted to see the cashier I would've hit the little button that said PAY INSIDE.
Anyway, lol, I was so mad I just got in the car and tried to remember $34.00 because I would forget for sure. FOR SURE.
As I'm repeating $34, $34, $34, this car behind me starts beeping his horn and I'm like "WHAT?" cuz I was mad,remember?
He yells out the window, "Your gas door is open and your gas cap is hanging out."
I thanked him, fixed it, hopped back in and drove off thinking they'll never believe this at PC.
