I personally love tipping. When you can tell that someone actually makes a real effort to take care of the customer and do their job well, there's nothing better than being able to make their day (or at least, make it better and show your appreciation) by going above and beyond.
Most of the situations in which you tip are already signs of you not being too frugal. If you are eating in a restaurant, buying coffee out, valeting your car - you are not penny pinching so you can give someone a few extra bucks without breaking your bank.
Of course you have to be culturally sensitive. In the US tipping is expected and appreciated. Other cultures don't expect it and would think it's rude.
