mpany pays in the UK, as a result the service is terrible. So we already do, do that. It doesn't work.
I order my food and drink, I get my food and drink. I don't go to a restaurant to make small talk to the waiter.
If there are any problems I call them out on it, and it gets fixed.
If they are very good, i.e. dealing with other problems such as lack of foods, or odd customer requests, then I tip around 10% - thats the only way I got tips when I worked in hospitality, it seemed fair to me then and it seems fair to me now.
The idea that tipping increases performance isn't really true, I've seen terrible waiters in the US, and they still expect their customary 10,20,30% - and boy do they get up in arms when you refuse, and point out they got your meal wrong, and your drinks wrong twice..
