My GOD! I am amazed that a member of the generation that I despise (no offense to you...I don't know you from a hole in the wall) knows about the quarter on the string trick!!!!
Seriously!!! :Q
I used that trick to get free games on....READY?
A SPACE INVADERS ARCADE MACHINE! :Q *(TheEvil1 says "holy sh1t, you are OLD, MichaelD!!!!!)*
I didn't think anyone actually tried that old trick anymore as machines have gotten a lot smarter. Or, I should say, the people that design the coin mechanisms have gotten a lot smarter.
The only way you will get free washes is to break open the coin box. NOT to steal the money..allthough that is a nice side benefit...so you can toggle the switch that the quarters bounce off of on their way into the coin box, AFTER they pass through the complex anti-quarter on a string-mechanism that has thwarted your efforts as so far.
Don't do it. Your friends will rat you out. (People you meet in college are not your friends....trust me) Just phone Mom and Dad for laundry money. OR get a JOB!!!!!!!!
Good luck to you, Stinky Laundry Man.
