Trying to understand how all the $20 USD bills in my wallet from last Friday morphed into $1USD bills today... Then remembering back several years ago it seemed everytime I spent a $20, the clerk had to make a production of drawing on the bill with some special pen. Or, a few stores had some sort of machine. Anyone recall that and/or why retailers stopped? I have not seen anyone check for years.
Seen it done with larger bills. There are ways of checking that aren't obvious. Assuming the cashier has been trained to do so. The pen can't tell you that the fake $20 was made from a real $1. There is a reason other countries have different sizes for the different denominations.
Yep; in my high school days, working as a fast food shift manger, I've found a few of those. One actually made it into the safe. Needless to say, we 'shift managers' all got a stern talking to. We were all pretty sure it was the owner or owner's daughter that put that one in the safe; since they both had the attention span of a gnat. Hey, they made me shift manager @ 16 and I didn't really know them. I believe that would now be called 'hostile work environment' and/or harassment.
I always carry cash but rarely use it. I've found that in a post disaster situation, if can be sort of handy to have access to actual cash money - and I work in telecommunications - which DOESN'T always work.
