I remember years ago there being an issue with a restaurant chain having a strop because they had to pay their staff a full wage rather than them having to rely on tips to top them up.I thought tips have always been about reward for service. The tip the bellboy for carrying your heavy bags up or tip for good service at the restaurant. It is a reward not a top up of low wages. Or at least that is the UK tradition.
If we tipped everyone for good service, it would be huge. The person who checks you in nicely at the hospital, someone in the supermarket who helps you find a food item, the phone engineer getting your internet reconnected, the gas man who sorts out a leak, the bin man who puts your bin back nicely, the person who changes your tyre, and….
It’s an antiquated habit
(but I do tip when I want to. )
