I’ve never understood why people aren’t clear on the concept of “legal tender.” If I am a storeowner, I can refuse your payment of a $100 bill for a pack of gum.
If you go into a party store in the middle of the night, they aren’t likely to have the change to break a $100 for a purchase under $1.
how about the concept of “if I have to take 10 minutes to count up all your change, I will lose several other customers and even more money”
“I can refuse your payment of a $100 bill for a pack of gum.”
That would make me suspicious. I would whip out my counterfeit detector pen and check the bill. If I see black would have the secret service on the courtesy phone in New York minute.
