To pay for an $8.65 meal with 6 dollars cash and the rest in change (10 quarters, a nickel, and a dime)
I really want a burrito bowl but I have limited cash
If it's all legal currency that's accepted in your current location, then go right ahead.
Cashiers actually like getting paid in coins, cuz they often run out of it when they make change throughout the day.
They just don't like counting it themselves, so count it out at the counter in front of the person taking your order.
