Visiting the US soon - do I really have to tip?

Hey Folks!

I've been living abroad for over half my life in a country where tipping is not the norm. At most you would round up. 19€ bill? Here's a 20, keep this change.

Going to the US soon to visit family and the whole idea of tipping makes me nervous. It seems there's a lot of discussion about getting rid of tipping, but I don't know how much has changed in this regard.

The system seems ridiculously unfair, and that extra expense in a country where everything is already so expensive really makes a difference.

So will AITA if I don't tip? Is it really my personal responsibility to make sure my server is paid enough?
