Someone posted in that thread about how people would like it if every person faced such treatment. If gay couple was marked down as "gay couple" or black family was marked down as "the blacks". I think it may have been Mercury Fred that made the post. Because it was him, I didn't reply, but my first thought was that would be great.
I can just imagine my bill. "Another white dude" "neckbeard" "Eats alone" "hipster trash" "Chandler Bing"
I think it would be great to see how people categorize others in order to maintain clairty in their job. Also, everyone would be able to see how others view them. You might get gay boy one day, but maybe the next day the waitress marks you as dandy. I would go to a place like that just to see all the awful names people would call me.
