In reflecting on this thread and the race situation in general I recalled 3 experiences I have had.
At around age 25:
We went into a local bar. I think it had a Irish theme. It was a bit of a dump. Dark and dingy. The place was occupied white locals who fit in with the dark and dingy atmosphere. We were young professionals, clean cut, probably dressed a little better than they were used to.
In short, they would not serve us. We were not drunk. We were just to rich looking for them. Not their kind. I recall being real pissed off. One of my friend convinced the rest of to just go. We did.
At around age 13.
We went cross country with a camper. Somewhere out west we had car trouble and we pulled into a remote restaurant in a forested area. My dad asked for water for the radiator. The guy behind the bar asked him if he wanted to buy anything. In short he would not help, likely because we "were not from around there".
Further in the trip we we sitting a roadside picnic table in Texas eating lunch. This car pulls up and a guy rolls down the window and says, "New Yorkers, huh!" and they then peel out. I suspect they saw our license plate.
I guess this is the closest I have come to experiencing what blacks (and others) may experience on a more frequent basis and with a bit more animosity.
On the flip side, in South Dakota, when we checked out of the campsite, there was a sign in the office that read "Police and Clergy Identify Yourself" My dad was an NYPD detective and asked what that was about as he pulled his gold shield out. The guys says they don't charge Police and Clergy and hands the cash back to my dad After several attempts to give the cash back to my Dad politely left and put the cash in a some kind of donation box that was just outside the door.
I tend to recall the last situation more that then the other ones.
