My husband was a recruiter for a while. Army recruiters get world class sales training, so he and I know all the tricks and can tell the salespeople what they are up to -- some of them have never heard the theory behind why they are told to start with 'How are you today?' and stuff like that.
Anyway, since my husband pulled recruiting duty, we are just so cynical. I do not like to be rude or mean because they are still human beings, but I also do not like to waste more than 60 seconds of my precious time when I know I am not going to buy anything.
Recently, a guy knocked on our door and asked how I was and had his product in hand. I told him "I am in the middle of doing something, short of sleep, and really crabby. If you hang around here for more than 60 seconds, you will be threatened with being thrown out of the apartment complex. Have a nice day." I grinned and waved cutely, like we were good friends. He picked up his stuff and backed off, not knowing how to react.
Three years ago, a charity called me, asking for money. I told them the truth: I would love to give to your charity but I just returned from taking care of my sister following her mastectomy. Try me next year. I have given all I have to give for this year.
A few months ago, someone called asking for money for research on some genetic disorder. I told them I would be thrilled to give money to their cause, but I have no money to give because I have my own genetic disorder and it costs me a bundle to take care of myself and I am deeply in debt.
I do not lie. I try very hard to remain polite. But I generally never say I am 'fine' when they ask how I am. I give them The Truth and their whole speil falls apart right then and there. lol.
Sorry for the length.
