In a slightly different story we had one of our troops that refused to buy his own shampoo and kept stealing / using other troops supplies. We'll one of the guys took to mixing his shampoo with "nair" at a 50-50 rate.
He then took the little freeloaders dosemitry radiation badges off the wall and took em back to our small portable x-ray we used to look at suspect packages in our EOD work. He cooked those badges really well with multi-pulses of the machine.
Now when our next radiation badge reading comes around and our troop's hair is falling out in small clumps every now and then we added some of the free special brownies made with ex-lax.
This freeloader then went through some pretty awful medical testing at the base hospital with high rad readings, hair loss and not able to control his bowels ect ect as the symptoms......... our luck he got 100% disability when he retired because of his "exposure"........
Stay Safe but above all else have fun at work !
