If the FFL holder suspects a buyer and still sells to them anyway, said FFL could be asking for some trouble from the ATF. Their instructions are to refuse the sale if you think something is hinky, not complete the sale and then call the local PD.
As for the OP, it looks like someone here has given you a good line on a better FFL to use, I'd call the manager at the Big R and tell him that 1) you will never spend another dime in his store, 2) you will tell everyone you know not to do any form of business with them and 3) you might tell him you question the legitimacy of this particular employees parentage and that until he rids himself of said bastard he's likely going to lose many more customers.
Whoa dude, whoa. Better make sure that's what happened in the first place before tossin the gas tank and torch through the window. I can think of more than one other scenario as to how this got kicked off.
Mom's comin' 'round to put it back the way it ought to be.
Anyone that thinks war is good is ignorant. Anyone that thinks war isn't needed is stupid.
