Happenings at PGA superstore

I was in the North MB store late Friday afternoon,  I was checking out grips & used shafts at the pro shop when a couple of guys arrive & go to the desk.....guy says to the shop worker " I bought this shaft yesterday & you were supposed to put a Callaway adaptor on it, I went to change it at the course today & it doesn't fit."  Worker grabs it, looks at it & replies it is a Callaway adapter,  did you take the screw out before you tried to install it? It comes with a new screw for the club head.  the guys buddy busts out laughing at him,   I just shook my head & walked away laughing too.
