I know they do it in South Africa (along with a "13th month" of pay), and I'm assuming the US too.
Outside of those two, I don't really know of any other Western cultures where tipping is much of a thing at all - let alone big tips at the end of the year.
When my dad sent me to the barbers for a haircut, he gave me a coin to tip the barber. I think the idea was that the barber might remember me (9 year-old kid)! I don't have much hair now, so I don't have to tip barbers. But I tip taxi-drivers, evern though I know I'll probably never see them again, and if I do, they csrtainly won't remember me.
I tip waiters, because I believe they depend on tips to get decent pay. I hate it that this is necessary. I also HATE that tips for waiters go into the tip-jar, and are shared by kitchen staff and management.
People should get proper pay. How hard is that to understand?
Maybe nowadays this is the Amazon and Deliveroo zero-hours-contract drivers.

The "sanitary operatives" in the UK used to ring your doorbell in the run-up to Christmas, more-or-less demanding a tip. If you didn't tip, then you risked having your Christmas rubbish languishing for a couple of weeks, or even strewed over your garden path. Happily, that practice is now ILLEGAL.
