I moved to a new city for college. I made a friend, who I considered well-off (he was also a bit heavier). One time I went to his place, and he wanted to have some snack, so he grabbed a jar of Nutella and some sliced bread. On a piece of bread, he put on a layer of Nutella that was not thinly-spread at all, that I thought "Oh, I didn't even consider that it's actually possible to spread a thick layer of Nutella on bread. I guess well-off people are different!"

A few of my friends and I have joked about something similar. You can tell a lot about a person's family's financial status when they were children based on how they build a sandwich as an adult. Slices of meat, what style cheese, etc.

Next step is to skip the bread and eat Nutella from the jar with a spoon.
