Hide it in your thermos

You do bring in a thermos to work every day. Hell, everyone does. The coffee they provide for the staff is the same stuff they serve the prisoners, and even at a fairly upscale facility like this, it's still pretty awful. The packet was already wrapped pretty tight; you'll wrap it in more plastic wrap, wedge it into the very bottom of your thermos, and then fill it with coffee. You've never known them to do more than unscrew the lid of your thermos, so hopefully it should go smoothly.

It only takes a few minutes to prepare the packet, wrapping it securely in the plastic wrap, so that there is no chance it will break open, and also so that you can cram it into the very bottom of your thermos so that it should stick in there. There's still plenty of room for coffee in there as well, as the thermos was purchased with getting you through most of a shift in mind, should you need that much coffee.

You leave the thermos on the counter that night, and have the coffee machine set to make the traditional full pot automatically the next morning. You sleep surprisingly well, given the various good or bad things that could happen tomorrow. You shower, shave, and get dressed, and both the coffee and the thermos are there waiting for you in the morning. You drink a cup, black, to get yourself started and get the energy going, then carefully pour the rest into the thermos. There's a little bit left over when the thermos is filled, so you top off your cup and sip at it as you make yourself your lunch to take to work, just as you always do. You don't know if you'll actually eat it today, but you don't dare do anything that deviates from your normal routine.

Finally, with the food packed into your lunch box, and the thermos held in the other hand, you head to work. You work at calming yourself down as much as you can on the way there, and think that you are more or less succeeding. You make sure that you stroll in through the special entrance for the guards during the same window as your usual arrival time.

Once you're inside, you face the classic scenario of a guard behind bulletproof glass, along with a locked door you need to be buzzed through. Derek is in the security room, behind the glass, and there is a little opening that you pass anything you are carrying through for him to check over before he buzzes you in.

"Morning John," Derek greets you, pleasantly enough. You return greetings as you pass your lunchbox and thermos through to him. He pulls them through the opening, then almost immediately slides them back towards you, apparently not even planning on opening up the lunch box.

You fight the urge to breath a sigh of relief as you reach out for your belongings, when suddenly Derek reaches out and grabs the thermos, right before you hand can grasp it. You feel a sick feeling in your stomach as Derek pulls it back slowly under the glass. He lifts it up, and shakes it slowly, letting the contents slosh around a little.

"Hey, John", Derek says apologetically. "My coffee machine is broken, so I have nothing other than the crap here. You mind if I bum a cup off of you?"

"Sure, go ahead," you say, fighting to remain calm. So Derek doesn't suspect anything. But you hadn't planned on anyone actually pouring some coffee out. You hope to God that the packet is wedged in there tight.

Derek pops the top off of the thermos, then unscrews the cap. He pours himself a generous cup into a mug permanently stained a light brown, apparently without any problems. He takes a deep sip of the coffee immediately, then sighs.

"Columbian?"

"Yeah, I'm pretty sure it is."

"Good stuff." Derek takes another big sip, tops it off, and then reluctantly puts the cap and top back on the thermos, and hands it back to you. "Thanks, John," he smiles. "I owe you man."

"Don't mention it," you respond as he buzzes you through. And then you are inside the jail, and on the way to your cell block.
