How do the Pizza shop owners know that someone ordering pizza is gay?
Do they deliberately flaunt it and tell you that they are before ordering?
Do they wear g-strings or dress up like Boy George like they do in gay parades before ordering?
If the people ordering the pizza did not want to make a scene, they wouldn’t say, and the delivery guy probably would not care.
It’s about making a scene. It’s amazing the things America will permit you to do if you don’t have to make it an obnoxious press conference.
