Yeah, this is too much nonsense for me.

If a waiter is comping something in exchange for a higher tip, that's not generosity or goodwill at all, it's a dishonest scam.

I will tip what I want to tip (often 0) without remorse and move on with my life.

Unfortunately this cancerous American system leeched into Canada, but we can still stop it, one $0 tip at a time.

I think the procedure is being misinterpreted. This isn't a scam, it's just a common social convention. It's not a scam by the waiter because they have a limited amount they can do this for and they have just chosen to do it for you.
