Jiffy Lube had 1,000 locations in the U.S. in 1989. According to my experience in the 1990s (limited mostly to the Midwest), quick oil change shops were ubiquitous even in small towns.
I’ve never seen a shop that will let anyone stay in the vehicle while it was being worked on, even for something so simple as an oil change. Where did you find one?
In the US, this is really common. There a few big chains, like Jiffy Lube and Valvoline, but also a lot of local places. Just look for "drive thru oil change" on Google Maps
