<human>: Condense the text into a few key points

Before you go calling me a racist, please read the entire details.

I have nothing against blacks (or any race for that matter), and I am well aware that plenty of blacks leave tips for service staff. This question came to me recently and I genuinely am curious.

I work part-time in a primarly white, high-income community doing kid's birthday parties. Besides simply setting up and breaking down all the equipment, we must supervise the kids and serve food and beverages to the adults as well as provide any other services they need (escorting, help carrying heavy bags such as gifts, etc). The majority of all the parties we have end with each of the staff working the party receiving a tip. On average we have 5 people working each party, and our average tip is about $10 each. If the host family is exceptionally generous, we may each receive a $20 tip.

Like I mentioned earlier, the town I work in is primarily white, so naturally we only get a small handful of black families come. The last party I remember working for a black family was a big one, as there were a large amount of guests that exceeded our average. The kids were very loud and wild, and the staff did a great job serving everyone and handling the party, and the family was clearly very pleased with our service. These factors are usually the recipe for a guaranteed tip, yet the family left no tip at all. Not even something small like $5 or $4 each.

Looking back from this, I realized that none of the black families we did parties for left any tips. I can't believe that they couldn't afford to tip considering that the town I work in is very expensive to live in. 

Like I said before, this is not meant to be a racist or offensive post. I genuinely don't know if this is just a stereotypical coincidence or if any other employees who regularly receive tips have seen this happen on multiple occassions.
<bot>: Black people never seem to tip me and my coworkers even after we provide them good service that they clearly enjoyed and I want to know if the stereotype is actually (somewhat) true.
