What is really bad is when you get your dongle caught in your zipper. Had a customer do that once, left it plugged in and then went running through the airport with it hanging out. Ran right into a woman and broke it off. We had to order a replacement dongle for him, he could not perform his duties without it. Took 2 weeks to get a new one for him, once his dongle was replaced, he was up and going again with no problems.
