I was a waiter in Myrtle Beach for 3 months while I was a student (7 years ago). I gave EVERYONE the same crack of the whip no matter what race they were. Black, white, hispanic, whatever - I was nice to them ALL. I went to America not really racist but I left quite racist after how badly blacks acted and had such a bad chip on their shoulder and rarely tipped. Their attitude was sickening to me. It left me with a bad taste in my mouth that is still strong. I fucking HATED seeing them after a month or two and generally avoided black tables.
edit:
a few examples
The only cool black table were a group of guys my age, about 4 of them. They actually tipped me the standard. 5 minutes after they left the hostess was looking for her phone, it was stolen. They were the first table in and out that afternoon (it was definitely them, lol)
2 black guys in their 30's came in and acted like twats. My gf told me after one of them asked her "had she ever had any black cos he had never had any white ass" and she never told me 'till they were gone because she knew shit would have went down bad (I was OFF THE HOOK crazy back then).
I was keeping an eye on them while she served them and they tried to leave without paying but I stopped 'em.
