>Also soft drink/water sales are not "close to zero". I don't know what you mean.

The comment was about the number of "lost soft dink sales due to reusing old/external cups".

The number of soft drink sales is high, but the number of "lost sales due to people refilling to often or trying to get drinks without buying them" is not.

At least not as far as I can tell in the McDonald places I know of.
