I work part time at a busy convenience store (to stay out of the wife's hair.) We have 28 gas pumps, only 4 of them are suitable for a truck pulling a trailer or a large motorhome. The parking lot is not big enough for those units to park ANYWHERE except at the pumps. The problem comes when it is time for the units to leave and the idiots in cars, motorcycles, and non-towing trucks will not give the large units room to get out. I have had to go outside to direct traffic to get the MH's or TT off the lot. When someone comes in and asks where they can park after filling up, we tell them to stay at the pump until they are done inside. they usually leave in 10 minutes anyway.
