[QUOTE=Raffles;14212618]We always use Addison Lee to Heathrow but don't tip. However, this is purely because I am following British unwritten custom, which is tip black cabs 10% but not to tip mini-cab drivers. There is no real logic to this, both are self-employed drivers.



I no longer tip taxi drivers, black cab or mini cab. Lets be honest, they charge enough. I have also noticed that black cab drivers no longer expect a tip.
