So Monday through Friday you have no contact with the outside world?! That sounds odd.
It is pretty standard. Fire Academy is the same way. It literally is "weekday" boot camp, much like I believe you cannot have access to the outside world except for a few hand written snail mail letters in the military during your boot or basic (whatever they call it)
Deerslayer, you have the opportunity due to your circumstances. That does not mean you will utilize it. These guys are jerks and they may talk down to you, but they quit and you have not yet. They earned it, you are still a bitch to a weed in a can.
Stick around and get some digits, these guys will be your best buds when shit does get tough, and it will. If Police academy is anything like Fire academy and firefighters/EMS culture/world, just because it is banned that doesn't mean there won't be a can somewhere there.
