Yeh it's Friday night, but I just had to chime in on this.....If you work at a station within 30 miles if the Mexican border, than for sure you have taken drug packages over the counter, or loaded them onto a CTV to be driven past one of those CBP checkpoints that are on the major highways just north of the border.
Hell of a lot safer to have FedEx move your drugs than to do it yourself. While I won't back up MFE on the 50lbs of coke, I do know of at least two CSA's that used to play amateur DEA man and get permission to have a package opened, and they were just about as good as a drug dog.
