Watching a Katherine Hepburn movie, and as usual they have these tiny cocktail glasses

5. It was a different time

and people weren't into huge portions of everything. I remember when a 1/4 pound burger first came along and was considered big. Those soda bottles used to be 7oz. size. Same with most of the glass sizes. If you look on line you can find pictures of old beer glasses for tap beer that were called "shorty glasses". If you buy dinner plates etc. from that period many are about the size of our salad/bread plates. Now you go to restaurants where they bring you a sandwich/burger that is stacked with stuff 5 inches high and more and is served on a plank of chopping board. People buy fountain soda in 2 liter and larger cups. Bars serve drinks in bigger and bigger glasses all the time.

People were smaller and, for example, wristwatches from back then are smaller diameter generally than today so they kept a proportioned look as to the size of the wrist.
