Trinity is right about clients messing with things when having their nails done . Some peopla are such fidgets, keep touching their hair.get fibres from their clothes....so very annoying. Wish they would just pay attention , because we will end up having to put the nails right.
Pedicures are a good chance for clients to have a drink offered without wrecking our work.
I think that serving herbal tea, tea or coffee in delicate china cups using mis -matched cups and saucers will appeal. Doesn't have to be expensive if you dont want to charge them. I don't, but I think CFBS has a good idea.
All the best
