Gas station guide

Ours is 30', with a toad hanging out behind. We use a lot of Walmarts, and haven't found one yet that we couldn't get into or out of. I always try for one of the end pumps, but most times we can use others. Worst situation so far (15 years) was the whole troup of yardworkers that filled the tank, then everyone went into the McDonalds to get breakfast and left the truck at the pump. I had gotten boxed in, and with a toad, could not back out. So, I just went in and got my breakfast sandwich also. Gas terminal attendant watched, so I asked if he would ask them to move so I could get out of the drive at least, and he acted like I has asked him to kill or insult someone. So, when I did get to the pump, I had the entire side of the three pump island and one drive lane blocked, so I put in $20 worth of gas, washed the windshield, checked everything, then went to another place and filled up the rest of the 75 gallon tank.
