Years ago a coworker (nice guy, good guy) had a friend who was a representative for some big golf equipment distributor.
He offered my coworker (John) a set of Ping clubs -- supposedly "rentals/demonstrators" -- for just an obscenely cheap amount.... and offered sets to any of John's friends, as well. John offered to set me up with a set because at the time I was sort of into golfing.
It just didn't feel right to me, so I didn't pursue it. In the end, John didn't, either.
Couple of months later John told me that the guy had been arrested on felony theft of... multiple sets of golf clubs, and he talked and told the FBI or State Police everyone he had sold the clubs to, and now they were in hot water.
So glad that I didn't take up that offer.
