Nice you could choose if you would like your gasoline with or without service

Still possible in some places. Especially cities with large numbers of retirees.

I used a full-service optional Shell station in Las Vegas last year. Unlike when I was young, full-service didn't mean in increase in the price of gas.

There are a few full-service stations around where I live. But you really don't need your oil checked when you get gas so unless the objective is to have someone else pump your gas in crappy weather there's not a not of point.
