Ok, Dragonball, If you've ever handled cash for a job at all in your life, you'd know that Money is quite possibly the most Dirtiest thing you could ever touch. Not only is handling cash with plastic gloves smart, its actually healthier then handling it with your hands.
For example: Humans on average touch their faces 5 to 10 times every 3 or 5 minutes. You're working cash at a resturant/gas station/video store/hell anything, and you get cash from a particularly grubby individual who pulls out a wadded up dirty 5-er and hands it too you.
see what I mean.
Its not stupid. Its pretty damn smart.
I personally work in a Resturant. We wash our hands once every our, or when we do anything that involves cleaning, handling cash then switching jobs, using the Loo, after a break, ect ect ect... you have nothing to fear about the person handing you your burger and fries.
Also, this is for you cashiers out there. You have the RIGHT to refuse any form of currancy. I've actually been handed a 10 dollar bill that was covered in dried blood, I just said "I'm not touching that", they then called over my manager who then said "Even I'm not touching that"
PS, didn't mean for that to sound rude...
