Not only do I remember those days, but I also remember being the one who did all those things! Summer of 1953, on US1 in Maine.
The place also had a small walk-up restaurant with burgers, hot dogs and, of course, clam rolls. And, overnight cottages/cabins - no, not a motel.
I think gas was 19 cents. Have no idea what the cottages were, but I'd bet no more than $10. Clam rolls probably $0.75 or maybe even $1.00. (There was a lobster pound just up the road charging 40 cents a pound!)
I think that if I'd received a tip, the owner would have taken it away! I wish I could remember how much I was paid. Probably $6 or $7 a six-hour shift!
