Exactly, you should always have the chauffeur wait outside with a selection of belts/table cloths ready for a changeover incase of clashing.
Why the chauffeur? Can you not afford a valet?
So it should be part of the price factored in, not as an "optional" (let's be honest it's not optional because it's generally a faux pas if you deny the tip unless service was bad)
The service in a Michelin restaurant is obviously good in comparison to a Weatherspoons, but it's also 20x more expensive and to get Michelin, that service has to be standard, so it's not good service, but standard service
I just don't see why it can't be part of the bill, instead of a peer pressured "optional choice", this isn't just for Michelin but generally any restaurant, just pay your staff a proper wage without relying on "tips" but more so for Michelin because of the price everything costs
Of course it's optional. You may get asked what was wrong, but you are well within your rights to demand it be removed for whatever reason. They can't force you to pay it.
Michelin service is very good compared even to the likes of Orwells or Inver.
The service does have to be
consistently good, but because what is considered 'good' is so subjective, the standard varies according to what the customer requires. If all you want is to be waited upon by servants, then that's what you get. If you want a warm welcome, with staff who are happy to chat with you, they'll do that. If you want ketchup with your thrice-fried pommes confit, that's what they will provide. If you want to feel lke royalty, that's what they'll do. If the guest asks for a substitution, they should not be told that this cannot be done - NOTHING within reason is impossible.
Staff need a tremendous depth of knowledge about the restaurant, the wine and food and how it's prepared (almost the same level as the chef), the etiquette, and everything else that goes with it. That takes a lot of training and study. This isn't just a normal waitering job - It's a full-on profession at this level.
But if you just want one all-inclusive charge, drop the 10% service charge and add 20-30% to your base bill. That still won't fully cover the 'proper wage' level, but it should help illustrate the sort of value these places attach to their service staff.
