not getting money's worth

I have been at concerts few times with friends, where the sound was way too loud. At that volume, it was no longer music. When I told my friends we should leave because we weren't enjoying it, their first reaction was that we should stay, so we wouldn't lose our money. But what we spent our money for was enjoyment. Not only were we not getting any enjoyment, we were miserable; we were getting negative enjoyment. The longer we stayed, the more in the hole we got. Also, life if short. The time you spend at a concert that is making you miserable is time out of your life that will not be available for actual enjoyment, or at least non-misery.
