Hello, is that the term for it? Red lining?

It is funny the last part of your comment. I was with my ex in St Louis and we were driving through to Illinois. It was evening time and we got pulled over by an officer. Now, my ex doesn't drive like I do. He is nice and calm, we were not speeding. I was baffled why we were pulled over. The officer walked up to our car and asked where we were headed. We let him know Centralia/Belleville area. He said that we were in a bad part of town and would give us an escort out of the area. REALLY? Wow, I admit I was shocked that this officer was so open abut it. I guess East St Louis is NOT a place to be at night. 

I believe that businesses have a right to serve who they want, when they want, etc...

It is business. If someone doesn't want my hard earned money, that is fine by me. There is someone else who does! ;)
