Yeah but, there are no local car hops anymore.
There is in Texas. Sonic (hamburger chain -- that doesn't list "hamburgers", only "cheeseburgers", in doubles and triples too, along with some other stuff.)
I saw one gal wearing roller skates. But most of them don't, I noticed. It may depend upon location.
Remember to tip them. Their pay is scaled for the employee to supposedly get a certain amount, but they never get what they are told they will when hired. Or so one young gal (who I think said she was hoping to go to nursing school) told me. Taxes are possibly taken out, as if they were getting tipped a certain amount?
The State government forces that, for waitresses in California (as if they were getting at least a steady 8%, unless that has gone up).
