I remember 17 however there a several I think I should know for some reason.
What's even more interesting is that some still exist here, those being...
Drive-ins - We have one that I go to a few times a summer.
Metal ice trays with levers - I've seen a few in a store around here, and I know quite a few people that still use them
Soda pop machines that dispensed bottles - We've got these too
Home milk delivery in glass bottles with cardboard stoppers - We don't get glass bottles but 99% of people can get home delivery twice a week. The guy come to my house once a week thanks to where I live. They give people a sign you put in your window, one side says yes and the other no, you simply turn it to tell them if you need them to stop or not.
