This is not quite matching the title. More of a Joke / Scam thread. I have two, the second will come later, saw a workmate do it.
At my previous job, the breakroom had a .60 cent soda machine.
When new employees were going thru orientation, I would always try to be there, and before they made it to the breakroom, drop a dime in the machine....
Once they arrived, I would welcome them, and clue them into the peculiar soda machine.
Even though it says ".60" , drop .50 into the machine, bang it hard on the side, then press your drink selection.
Nothing was funnier (and mean, I admit) than the next day watching them drop two quarters in, then bang the he11 out of the machine in an attempt to get a drink.
