Once, during a deal I was making at work, I placed the 40 bucks I got from selling 4 bags in my pack pocket with my ID, and when I pulled out my ID, i must've also grabbed (directly or indirectly) the cash and dropped it without even realizing it..

in terms of actual weed...I dropped a bag containing 8 more baggies out on a parking lot once during work as well the same way and I was running around like CRAZY hoping NO ONE would find it...everyone knows I smoke at work, they just don't see me do it or anything and dont' care enough to drug test but if they found that they'd KNOW it was me, or test me to be sure and I'd be fucked (still 17), so I ran in and out of the store countless times (mind you I was the guy in charge of the entire electronics department, including the register..people needed movies out of the display case and other needed to check out and I was running in and out of the store in a frenzy.)

Eventually I found it near a parked car and felt SOOO relieved.

Dealing really woudln't be worth it if I kept losing shit like that because I'd be losing much more than I'd be making.
