The rest of you are just regular folk looking for advice on how to behave at a convenience store, and I've got that for you. The first tip: Don't park at the gas pump.
Of course, I don't mean you should move your car first if you're only running inside to pay for the gas you've just pumped. That's absurd. Hey, you can even pick up a few items while you're in there. Gas prices are out of control, you've earned the right to lollygag a bit.
If you're not conducting gas-related business, though, you don't get to park your car in front of a gas pump. It's just common courtesy. The person arriving behind you who needs to buy gas might not have time to wait for you. If that person runs out of fuel and has to manually push their car around the lot until you finally emerge from your Slim Jim run to remove your vehicle from the gas-pumping area, well, that person is silly. He should have just left his car where it was when it stalled and then pushed it when a spot became available.
All your fault.
