Well I guess I am nobody 🤣 - I do still use cash, probably more than most people.
However I would still do same - if I caught a taxi and fare was 47:50 I would probably still say Make it $50
But the point is, it is still piddly amount loose change, keep the change type of thing
IF ANYTHING - whether it is literally coin change or not.
and I agree, nobody needs to do this, it is not an expectation - speaking for myself only, who very rarely catches a taxi or gets a pizza delivery anyway, that is what I would do.
