Badgering a seller

In my recent ads I have specifically stated that we am not interested in any trades at this time. Well I keep getting texts from people who are offering trades. So far I've been very polite and said, "No thanks, I'm not interested in trades at this point" or something to that effect. We've had several people come unglued on us when we say no. One guy even went as far as yelling at us, "Well you ! idiots!" and another guy who said, "I'm gunna come down there and kick your if you don't trade me.". That really helps your chances of ever doing business with us.

What the is wrong with people? It worries me everytime I sell or trade something with someone I don't know.

spent too much time on Craigslist
