Personally, I also found this interesting. I guess you can't please everyone. I waited tables for many years and I was shocked when I started serving to hear other servers racial stereotypes and I always tried to provide the best possible service to everyone. However, as I gained more experience I found that non-whites consistently tipped less than white customers. It would be interesting to see a study showing whether this was actually true or a self-fulfilling prophecy.

I've noticed that almost all doctors where glasses (or contacts). An opthamologist told me that several studies point to a strong association between reading in childhood and the development of myopia. So there might be some science behind the stereotype!
