These days I arrange my fill-ups to avoid New Jersey. Last time I stopped there, I had to haggle with the guy to put the last 4 gallons in my 12-gallon tank, because the wonky fuel neck would trip the auto-shutoff prematurely and he thought it was done. I knew how much fuel I'd burned and I could look at the counter and know it wasn't done, but Professor Petroleum was having none of it.

I don't care what the idea is, it's annoying, insulting, and backwards.

Oregon doesn't either (except in certain rural areas at night and that just changed a year or two ago.

It's super annoying, unless it's raining or really cold out.

Is there an expectation to tip or is it included?

Not anymore.

It used to be commonplace to tip gas station attendants everywhere in the US back when boomers were growing up; full-service was the norm and the attendants would check your oil and clean your windows.
