I'm going to blow my nose on the paper napkin in a cafe/restaurant and discard it on my plate with the waste food
Is this normal for you?
I hate the fact that we can't express our feelings on some things.
Is this your way of expressing yourself? If so, I think it's fine as it'll just be thrown away anyways.
I know but it's not a big deal.
Well as long as you are not sick I don't see a problem with it. You should have some respect for the workers and try not to get them sick if you can help it.
