I always feel the need to give a tip to a taxi driver, but I am starting to wonder why. He isn't giving me a discount, he is just doing his job. I already give him money, and then I scrape about for change, or say "keep that".
I am going to be using taxi services every day next week, and it will cost too much if I tip every driver for every journey.
Am I a miser for not wanting to leave a tip?
