On the Run is a convenience store chain and BP gas station. It is in a very convenient location for those who are returning rental cars at Lambert-St. Louis International Airport! How many times have you been on the way back into an airport, and not found a gas station nearby? Happens to me to any times — often you have to go out of your way to find one. Not so here! Paid at the pump — I note that the pump had a hand scrawled note taped to the pumps — requesting you press the appropriate button(credit or debit) before swiping your credit card. Never seen this before — this is the exact opposite procedure of other gas station pumps when using a credit card! Refueled and was on my way to Hertz!
