X No Change Please
This sign was intended to mean that you can not receive change from this cashier. But it sounds as if the restaurant does not want to receive change from you!
The Japanese translation uses the term 両替. We can assume that the intended meaning is お金をくずす (“make change”) and not, for example, changing yen to dollars.
But “change” is being used as a noun here (rather than the verb “make change” or “give change”), and as a noun it should mean 「小銭」, or 「おつり」, or even 「変革」! So “No change please” translates as「小銭を私たちに与えないでください」! (Native speakers will NOT think that “No change please” means “Please don’t ask us to make change.”)
Technically, 「両替は御遠慮下さい」 means “Please refrain from asking us to make change”, which is a natural way of expressing this in Japanese, but sounds strange in English. We expect a sign like this to tell us directly what THEY will not do, rather than asking US to avoid doing something.
It’s still possible to do this in a way that sounds polite, though:
O Sorry, we cannot give change
