I have been mistaken for a policeman many times, and even been given a discount too. The catch is, I was not carrying a firearm at the times! I have no idea why, once when I walked into Arbys they ask what I was there for and I said "uh, food?" and they laughed. They said that they thought I was a cop and I "walked like a cop".
Strange, but there you go. Wendys has given me a discount two or three times now. No idea.
