Stopped by our company where I am the manager. Constantly tried shoving their product (penetrating oil) down our throats. Told them to stop by another time since we were slammed with work. They did and when I mentioned again we weren't interested in their gimmicks the sales guy wanted me to explain. I did and after that he went bizzurk complaining and turned and walked out mumbling words and slammed the door. All because we didn't buy a $6 can of penetrating oil.
