My local cafe used to have a separate jar for tips, it has now added a screen to the card machine that says 'Leave a tip 10% or 15% or no?' And you have to choose - whilst the assistant stands before you & can see what you're doing. A standard lunch in there with drink is £14 (up from 12). I will no longer be able to go as it's just too expensive and I hate the added pressure of being watched while I decline to tip. I know people will probably pile on telling me I'm being unreasonable. But that cafe has just lost my business at a time when they need it more than ever surely? How do you feel about tipping?
