Nicely said! Great point

On that note, I once purchased a simple cup of coffee from a Dunkin Donuts and I paid cash for it. To my surprise, the cashier took it upon herself to take her own tip from the change that I was owed, so instead of giving me my change back, (no she did not forget I was owed change) she held onto it in her hand and was about to put it in the change cup when I politely requested my change. She gave it back to me with some attitude. I was flabbergasted at (1) the presumption that someone felt that a cup of coffee (pouring coffee into a cup) deserved a tip and (2) that the cashier felt entitled enough to think that they could make a decision of what to do with my money that I earn through my own hard work!! Mind you, the change was under a dollar, yet regardless of the amount of money, the principal of it is what matters!
