I don't tip my hairdresser as he comes to my house to cut/colour and I wash my own hair..though I do feed him and keep him well watered with tea. I have known him for about 20+ years and tipped him when I first started to go to him in a salon but we are friends now..he came to my DDs wedding as he does her hair, her sister's, my DH and the DGC too! I have introduced other friends who also use him. I buy him a birthday and Xmas pressie
I usually add a bit to the fare for taxi drivers but only if they have made some sort of effort!
Waiting staff get a tip if not already included and then 10%+ depending on quality of service .
It is difficult because many staff can rely on tips, which is wrong they should be paid properly in the first place.
I did receive lots of flowers, chocs, mugs, pens and toiletries as a teacher which was lovely and appreciated. Nowadays, in many schools, the PTA class rep sends an envelope round for donations and then uses the collection to buy gifts for all who work in the class.
It is a bit of a minefield though!
Bought the wrong Hot Cross Buns 😩
