and some bastard pulls out a shotgun, or revels hes strapped with explosives? my wife calls, my son got hit by a car?
or how about these scumbag hotels still trying to cling to an obsolete business model, by playing dirty.
it is also quite possible your active jammer knocks out the remote base station, bring the whole site down.
if a company hates phones so much, fire people who use them during work. I hate companies that treat their employees like children/slaves. My job is more dangerous than theirs 100% guaranteed, and I would quit on the spot if they told me I could not use my phone at work. At the same time, people who are yacking on the phone all the time, they dont last long. If your phone interrupts you during an operation that someones life and limb is in your hands, your gone. Big difference between making a quick call while waiting on something, making a call that briefly interrupts your work, constantly stopping work to answer calls, like me but its work related, and letting go of the rope to answer the phone and killing someone.
