Sounds like you encountered the young george floyd.
Interesting that it passed the marker test though, must have been a "washed" bill. I think they work on the paper mostly. You need the light too and maybe even the scanner for the metal strip to be sure.
The most important thing to check for is a large, uncommon bill ($50 or $100) with someone trying to buy something small, that they can walk away with. Older bills are more suspect than newer bills.
But I have made similar comments about this in the past.

Small…..like a banana?
Anything that costs $5.00 or less, although I never sold bananas.
Merry Christmas and New Year to you tho, I hope you are still making content, we all enjoy it.
Yeah, When you are trying to buy $5-12 with a hundred that is usually a red flag.
I do always ask if they can break a $50/100 so maybe I seem sus sometimes but I don't exactly look like the type that is going to lie/rip you off if you get what I mean.
