I carry it, and apart from a couple of specific, non-essential places, I’ve never been denied when using it. Businesses are often happy to have it.
One place I visit only accepts cash and has an ATM inside their store. Another (cafe) is like 5% off for cash (not much given the scale but adds up) so I bring exact change.


























And also, I’ve had to wait for a teller just to divide into smaller notes for exact change, much quicker and more respectful, especially in businesses which aren’t retail
