strange door to door security “salesman”?

A door to door salesman came by our house last night. I thought it was suspicious b/c not only did he not have business cards or pamphlets, but he stopped by around 9pm. It made me feel like someone would break into the back while he was talking to me on the front porch. Nothing happened, it just seemed really weird.

He was a kind of clean cut looking white guy, glasses, maybe in his 20s. It just didn’t make sense that if he was “selling” something that he wouldn’t have any brochures or anything. Anyone else see this guy?
