The soda machine at work is conducting psych experiments.
A soda costs 60 cents. I have a quarter and four dimes (65 cents). When I put in my money, the machine says "Please use correct change," which means that it doesn't have proper change to dispense. Fine. I push the coin return button so I can bug our accountant to switch my one dime for two nickels.
Clinkety clink. The money falls into the hopper.
It's two quarters, a dime and a nickel.
Which I promptly put back into the machine, save the nickel.
I put my mouth close to the coin slot and whisper "Nobody likes a smart ass.*
There is no response.
I get my soda, though.* I was lying. The only person who doesn't like a smart ass is the priss of the group. Everyone else loves the smart ass, but I wasn't counting on a soda machine to know that.
