Sorry my point was that you said they should pay staff better and no tip will be needed - I was making the point that we never actually check what wages they are being paid - it might be sufficient enough to not need a service charge or tip to top it up.
If I paid my staff £100 an hour and no service charge was included I’ll bet most people would still tip regardless. Fact is we moved away from needing to tip with the minimum wage being introduced (why would we not tip some minimum wage roles but tip others).
Japan is a good example where they don’t have a tipping culture at all. Several Japanese restaurants in London actually refuse tips and say so on walls.
