Lesson learned the hard way: Don't lend what you can't afford to lose! That applies to the house cues you are letting people play with. If their expensive cue is at home you might loan them an equal cue. However, if they are used to playing with one piece house cues in bars they are going to use yours the same way.
Being nice cost me the shaft I gambled with six or seven nights a week. Tapped a ball with the tip. Not something to cause a problem about 999 times out of a thousand but this time the last two inches of the shaft snapped off!
