I just had one last night, had me chuckling. Was pulling in to a Wawa to fill up, and had a super duty towing a trailer in front of me. He turned hard right to circle the pumps, so I went left around them on the other side. This Wawa has a total of 8 pump islands (16 pumps) of which only 2 islands on one end have diesel, so anyone getting diesel has to fight for those 4 pumps.
So I knew the super duty was headed for diesel, but he'd been in my way, drving slow in the left lane, for 2 miles already and I didn't care any more... Swung around and got to the first outside pump that had diesel, the inside 2 were blocked by a 24 foot truck. I figured I left enough room in front of me that the super duty could get to the pump if he wanted; but I guess he didn't agree and circled back around to pull in behind the 24 foot truck.
I opened my fuel door, added my Optilube, and was putting my card in as the 24 footer pulled away and the super duty was able to get to a pump as well. Just as I finish paying and was about to pull the handle, he jumps out and comes over to me; gives me a quick look like he wanted to fight and said "These pumps are for diesel, you should stay at the gas pumps so you don't block the guys who need them!"
I laugh, look at him, pick up the diesel handle, and put it in my car. As I start it, I just stare at him. He looked at my BMW, looked at me, looked at the green handle, and shook his head. I said "It doesn't have to tow 10,000 pounds to take diesel bud, I thought I left you enough room in front of me though..."
He looked again, mumbled something about the trailer and walked back to his truck. I just chuckled...
