Now, please DO NOT take offense to this... it is meant in a truly appreciative fashion, 'k?
My first thought upon seeing the subject on this thread was, "That's got to be knifethrower!"
I run a business that has a misleading name. Despite the fact that we're "Astral Products," we don't actually
produce anything. We do powder coating and sandblasting. So we get all kinds of calls from vendors offering to help us with our shipping solutions or stuff like that. I've NEVER, in all my days, heard of someone just wandering in off the street to a business - that ISN'T obviously a shipping business - and asking a total stranger to ship something for them.
I'd be just as suspicious and reluctant to go along with that as your boss, frankly.
