There was a place like this in Vancouver, no idea if it is still there.
The Elbow Room. “Food and service is our name, abuse is our game!”
One of our group asked for water, he got told his legs worked and he could get it himself. The food was amazing, although we did get told off for not finishing our plate.
First I was asked politely to not swear, even if I was not a customer facing employee.
Second time I was cautioned was because I’d switched to swearing in another language. Manager thought it was hilarious, but they still knew I was swearing.
I spent the next five years being increasingly creative with how I swore. A temporary (and loud) revert to English swearing when I was in a workplace accident was kindly ignored due to circumstance.
There was no third warning.
