Here, unfortunately, YTA if you don't tip. I forgot once and had the server run after me to make sure something wasn't wrong. Some service folks take it personally if you don't tip, which makes sense given that their employers don't pay them shit. So yeah, you the customer foot the bill for ensuring these people can make ends meet... as if giving the restaurant your custom wasn't support enough.

The problem is that, like most other industries here in the US, the system is rigged against the working class. While not all restaurant owners intend to fuck over their staff (especially smaller, local places), it's how it works. Now, some places will automatically add gratuity to your bill under certain conditions, so check your breakdown to ensure it's not already included. This is becoming more common, which irritates me since I scale my tip based on the quality of the service rendered.

Also, we know it's expensive here. Don't bother coming here to complain about it, we do it enough ourselves. Tipping is here to stay for now and I don't imagine it changing for quite some time.
