Don't whistle at me like I'm a dog.

I'm on lunch right now. Thankfully. Earlier, a guy decided that he wanted to get my attention while I was working. He thought it was a good idea to try to call me like a dog. Literally. He whistled and everything. I ignored him and he gave up after a moment. He walked off talking to himself about how allegedly rude I was. If he had addressed me like a person, I would have seen what he wanted.
