I can relate to that. I have a picture of me as a girl when I was a car hop, with the menu and prices on a board behind me. The hamburgers were 39 cents, added cheese 5 cents more.
But when you take into consideration the wages paid then, the prices were in line with them. I think at that time (early 1950s) we got the magnificent sum of 75 cents per hour and we worked mainly for tips. We were all sure to be on the ball and cheerful ALL the time, made more tips that way. We were all also all the time trying to find ways of doing things that pleased the customers.
Now when I go to a store and try to find a sales clerk, they are busy, almost rude, don't know (this is a popular response!!) or simply impossible to find unless you go to a cash register and wave money or cards in the air. I've debated screaming at the top of my lungs but haven't gotten to that yet. Maybe next year.
