"Chili" is a pepper. Chili con carne is the traditional dish. There's no dish called "chili". The version without meat is an adaptation that came later.
Because traditionally both of those recipes are not vegan? Chili is meat based and pumpkin bread has eggs. You didn't make chili and pumpkin bread, you changed the recipes. They feel the need to indicate that somehow.
I don't know your family, so I don't know if they're doing it to be annoying, I guess if they're also calling your salads vegan salads, that would answer the question, but I don't see any harm in them labeling the vegan food you make as vegan food. They still eat it right? They're not shit talking it for being vegan are they?
Last time I was at an arcade and I saw someone win one legitimately, they had to take the box to the owner of the place to get the actual prize from the back room. I don't know who ran that machine but you'd have to bring it them. But like the other guy said, they're rigged as fuck and have a set win rate that only happens after so many attempts, so if you did try and bring it, they'd check the machine, see that it shouldn't have paid out and would know you cheated immediately. So you would've been screwed either way.
Do you mean battle tested? Lol
