A salesman enters a barber shop for a shave. While the barber is
foaming him up, the salesman mentions the problem he is having getting a
close shave around his cheeks. "I have just the thing," says the
barber, taking a small wooden ball from a nearby drawer. "Just place
this between your cheek and gum."
The salesman places the ball in his mouth and the barber proceeds
with the closest shave the salesman has ever experienced. After a few
strokes the salesman asks in garbled speech, "And what happens if I
swallow it?"
"No problem," says the barber. "Just bring it back tomorrow like everyone else does."
Moral of the story. True sales professionals realize that if you
don't know or understand everything about a given situation; it's
probably best if you just keep your mouth shut.
