Two of us went out to eat at a restaurant. Our waiter - a young lad who looked about 21/22 - got us seated at a table. Upon getting us seated, he noticed that our table was visibly dirty with crumbs from the people before. Instead of grabbing a cloth and wiping it, he decided to just brush the crumbs off with his hands (and not come back to wipe it). AIBU for not wanting to hurry back?
