In my area we had an issue with a major chain Hotel using 462.725 (one of our repeater pairs) for their business comms on commercial radios. After we researched and verified that there was no possibility of them having an ancient license for Non-Individual on GMRS, I politely contacted them on their frequency in an attempt to explain the situation. The Manager got on the radio telling me she was going to "Call the Cops" because I was not allowed to use their "channel". So I stopped at the hotel and again, politely, attempted to show them the FCC regulations and offer them a solution when the manager freaked out and called the police. Because I was on their property I simply left shaking my head. Needless to say I made sure they got a letter from our northwest FCC Representative Binh Mtuyem out of the Portland, Oregon area. We've had a few other businesses pop up on GMRS and most are polite and will move to FRS once it's politely explained to them, but there are still geniuses at gas stations and hotels that love to wander into GMRS then cuss and threaten anyone who tries to help them follow the law. Oh well! On a trip through Sisters, Oregon we had a Hotel/Resort employee on a MURS frequency we were using for travel comms tell us they "Owned" this channel and we needed to immediately get off of "his" channel or he was going to call the "FBI". That was a fun conversation! LOL
