It's really good. So far the "Claw of Shame" one has been my least favorite, which is probably a good thing because it's still hilarious, just a little over the top, kind of like the later seasons of Trailer Park Boys when it sort of forgot it was a fake reality show. Still great, just a little too unbelievable.
I've only worked at convenience or liquor stores in two states, but consent was all that mattered if you were going to get trouble via a sting. So if someone comes in to buy a pack of cigarettes or a 40, shows me an ID that looks sketchy, or plays the classic "shit I left it in the car but my girlfriend's got my keys at the bar" routine, whatever. Basically, if I asked "what's your age/are you over 21" you were in the clear because in a sting operation you can't lie as an agent; you're basically under oath and sort of a human warrant.
