this same question relying on emotional thought rather than cold logic was around at least 20 years ago.
In those days, the $30 purchase was a bottle of scotch ordered by 3 friends sharing a motel room. (Scotch then was a lot cheaper and watches a lot dearer.)
The answer is obvious if you don't go where you are being led.
The $30 watch/scotch turned out to only cost $25.
The 3 guys collectively put $30 in.
They got their scotch/watch for $25 total.
Each got $1 back so they paid collectively $27.
This $27 equates to thei $25 purchase plus their $2 tip.
There is no missing $2.

ps. Don't be led into the way you think about anything.
Think for yourself.
