I think people weren't as greedy back in the day, or perhaps it was considered rude to grab huge portions of stuff because resources were more scarce and/or your host not always that wealthy? Anyway, I have a tendency to pick up beautiful old coffee cups at fleamarkets and garage sales and so on, and they're almost always super tiny! All of my coffee cups from the 1960s especially are so small it'd be considered rude for me to serve someone using those- it's the equivalent of a thimble to a washing bowl, size-wise... Might be good for espresso/americano, though. I only got them for the beautiful patterns anyway, so perhaps they could be used as planters or vases instead... Not sure how many I own, the old ones are more precious so I mostly use new cups to actually drink coffee or tea from... hah.
