Lisa, I know what you mean. Friend of mine worked at the gas station couple of years ago. He was told to do the same thing. Just give the money, no matter what they do, even if they just ask without mention of any weapon. He decided to be a smart ass. Some kid walked in with a knife and ended up getting hurt. My friend smashed kids face against the counter and took the knife away. Guess what? Cops came and gave him shit.
randas,swatt13, Brother_J, one little "lead ball" is enough to send a person 6 feet under. Willing to take you chances and see whether or not thug has a toy gun. Go for it.
Thing is, if you use airsoft to blind 15-16y.o kid who broke in your house and not threatening to kill anyone you will probably end up paying him for a loooooooong time. If that kid will shoot you with a real gun he'll probably end up spending couple of years in the box plus probation time. That's it.
