They were very polite by never introduced themselves; Which at the time, I took no notice of.
They told me that they were doing a project for their class (never a school name nor type of class or anything) where they needed to talk to people to help improve eye contact, speech, not spitting on people, etc.
They asked me a few questions what I did for hobbies, what I was going to school for, that kind of thing. Then explained that they were selling magazines for a trip to Bermuda or Cancun or one other place. They gave me a couple of stock cards laminated in some cheap thick plastic and explained how they got points for selling magazines. These cards were nothing more than a bunch of hobbies on a piece of paper. There were no magazine names or anything. This is what told me there was something wrong. Why wouldn't they advertise the names of the magazines they wanted me to order?
I explained to them that I didn't have any money. They went oh! That's okay! You can still help us get the points that we need. All you have to do is write a check and subscribe to the magazines. Then cancel within three days and you won't be charged. They tried to tell me that I wasn't supposed to call the bank and cancel the check because I would end up with a $30 fee.
Luckily, I knew that this was ridiculous and sent them on their way.
You have to be careful of these people. Unfortunately most of them are scams and you will never see the magazines or your money ever again.
