In most places in the world, tap water is not safe to drink out of the tap, and thus,not safe to wash vegetables for salads, make ice, etc. So in these countries, does every restaurant have a filtration system? Do chain restaurants have filtration systems? Or is the tap water just used regularly? I know it’s dumb but it’s one of those things I just don’t get.

Usually it’s safe for the locals to drink. So that’s good enough for most of the customer base.
