Parking in front of the one ethanol free pump should be a flogging offense.

Too gentle.
Parking at a pump should be a Game of Thrones behavior modification program offense. (Heads, pikes, walls.) If businesses would protect the interests of the decent people by towing anyone who stays at a pump for 15 seconds longer than it takes to buy fuel, or who leaves their vehicle unattended at the pump for any time at all, the world would be a better place.
When my wife and I travel, whoever needs the bathroom first goes in while the other pumps fuel. We swap roles if the fuel is not done when the first comes out of the building. If we are really lucky with the process, the dogs get taken to a proper spot to pee while finishing the fueling. If not, one of us moves the car and the dogs are taken out while the second person hits the bathroom. If we want drinks or something, person #2 gets them during the dogs' pee break. Any other protocol is too inconsiderate for others.
If when we move the car it is too hot for the dogs (about 60 if sunny), it gets locked up and left running so there is AC. We have cheater keys just like cops, and if someone wants to try to steal a car with 2 Rottweilers in it, well, their estate can pay for service master call.
This will change when we start using the RV, which will have 300 gallon of diesel and 23 of DEF, but only in the details.
