Leaving a Tip...

How Often do you TIP? Once I went on a trip to Vegas and I thought to myself TIPing IS OUT OF CONTROL. We had to tip the door man, and the hotel clerk, and the taxi driver, not to mention the waiters at all the restuarants we ate at. The TIP game in VEGAS was insane. But with that I say if you expect good service employees expect good tips. But who do you tip, when do you tip and most importantly HOW MUCH DO YOU TIP? What surprises me the most is that as African Americans we often go to a black owned establishment and tip lightly but when we go to a white owned establishment we tip more. Why are we not supporting our people as we do others...
