I think the funniest one is sausage. They've just got a sausage box. Literally a wooden box to put your sausage in (dried cured sausage, not like...straight out of the meat grinder sausage.)

Want some sausage? Just find the sausage box, pull out your sausage, throw it on top of the box, cut a couple slices off, then put it back on the box.

Butter is obvious, but butter is sold in 250g blocks which are about double the size of an American stick of butter, so that's a fucking lot of butter to just leave sitting out. So you can just do like a quarter a time and leave it in a covered butter dish on the counter with the rest in the fridge.

Cheese can get disgusting. Especially if it already starts out smelling like moldy feet. Even covered in a cheese bell, you can get some horrendous smells permeating the house.

A general European one is eggs. In the US we wash eggs after they are laid to help prevent salmonella. This washes the natural protective coating off so bacteria can get into them easier, so refrigerating them helps slow that bacteria growth which makes them go bad. In Europe they vaccinate the chickens instead. Eggs are sold unrefrigerated and are usually shelf stable for 3 or more weeks.

But I don't really make fun of them for that one.
