As far as whinging about mytaxi is concerned I'll have to retrain my typing finger to omit the discounts of up to 36% bit. I know some will argue that free waiting time is a discount but, to be fair, most passengers only take a minute or two which, IMO, is generally reasonable.
I guess we'll have to wait to see how Whistle reacts, maybe I will be able to whinge about it forcing drivers to give discounts of up to 36% when it gets up and running?
