Do you tip in restaurants?Watch
For example on fathers day i was in a restaurant having dinner. I noticed the waiter standing around looking at his phone. I could see people waiting to be seated and people who hadn't ordered. So i gave him the tip that he was there to work not play with his phone.
Generally between £10-£30.
It depends on how good the service and food have been.
But I only pay the optional service charge if the service, food and overall entire dining experience has been flawless and I'm sure that the service charge is not sneakily being diverted to boost wages to nmw/nlw levels.
I used to more with cash but with card I tend to just go with whats on the machine.
Probably 5-10% in the UK, 15% in the US (always tip in the States).
