Don....the UPS guy who didnt want to talk to you....
did he look broke?
did he look like he stayed up late working on his hobby?
were his fingers cut?
did his clothing have grease on them?
was his credit card max'd out?
did he have a 9/16" box wrench in his pocket?

If any of the above are a "yes" he might be a hot rodder
and "acquired" a few parts from you.
