I was approached by this man at an expo in Minneapolis about doing a 'trade' for a service I was offering. He was offering free two nights and three days at resorts and hotels around the country. When I called him later to schedule the hotel visits, he informed me that there was a $25 'application fee'. When I told him that that was not part of the trade, he became verbally abusive and insulting.
I did file this with the Better Business Bureau in Minnesota, but it was never resolved.
