Nothing new about this, any one who has a successful vending business, can expect to be aproached like this from time to time. After a while it gets old I know, but it is part of the business we chose.
As the economy gets worse it will happen more and more frequently. The situation this presents is one of the dirty little open secrets of our vending business. We all want to help, thats why we are on this forum, but there is a limit noobs don’t understand. I will be glad to help, but I’m not going to help you, make my life harder.
Give them the RF IP. Or get a contract, 20 percent of their profits, and put them in business across town.
