Just that really.
It's always so awkward and feels so patronizing. And now that the minimum wage is going up significantly surely employers should be paying their staff sufficiently?
Up until now I have always tipped - £10 to my hairdresser each month, 10% to taxi drivers, waiters, etc. but actually everything's so expensive anyway (£169 at the hairdressers this morning! 
) that I kind of feel like I am paying enough already!
Is this really mean of me?! Do you all tip?
