many cashiers are young so when you flip something a bit different out there they become alarmed maybe even stupid....LOL
People have sometimes looked at me weird when I tried to spend $2 bills, or even half dollars, but I've never had anyone refuse to take them because they suspected them to be counterfeit. I've heard many stories that it happens sometimes, but it's never happened to me yet.
Quoting myself for a good reason. The story I explained eons ago was actually about a woman my mom worked with, not a woman my dad went to school with. I've heard so many tales that they're getting mixed up just like that.
I have at various times, spent all of those things except for the silver certificates. Not all at once though lol. I can still remember as late as the mid-1980's people would occasionally have Ike dollars in their cash drawers. Extremely rare these days, but where I work as a cashier we still do get Sacajawea, presidential, and SBA dollars from time to time (the public transportation network gives these out as change when people buy tickets with cash).
Sort of an opposite anecdote - my daughter worked at a food truck and the owner stocked the register with $2 bills. It was easier to give out change with them (lots of $11 and $13 items I think). She never said that any customers complained.
Forgive me for being a bit off topic. Years ago I had a really crusty gal working for me as a cashier. A customer handed her a $100 bill. She laid it back on the counter and told the guy that he needed a better counterfeit to fool her. The guy grabbed the bill and ran out the door.
