Yes, gas stations will rip you off all the time. I just put 16 gallons in my car (first fill up with this car for me) and the guage said there was 2 gallons left. I filled up a 5 gallon container in the spring with nearly 7 gallons of fuel and it was not ever completely filled. I went inside to complain and the guy refunded my money and placed an out of order sign on the pump.
