It’s not a problem over here (yet?), but tipping when you’re in the US is a massive con.

Standardised tipping. Not tipping if you’ve had good service, just tipping cos that’s the done thing.

I remember last year we went to Tiger Woods Popstroke, like a fancy mini golf place. The girl who we paid to get in literally clicked a few buttons on a screen, then handed us the balls. She got tipped $20 for it, by the guy we were with. I think it’s insane.
