Re: I'm INHUMAN I tell ya!...
In one word: reassurance.
Its the reason my dad can't buy a TV online, while I can. Our comfort levels are different. He has to go to a store and see it for himself. I can make a decision on specs alone.
Another reason: saving ass.
If the deal goes south for any reason, no one will be able to tell your contact person: "you bought the product without even meeting the vendor?"
Most likely, you will meet and interact with more than 1 person. Just so the blame can be avoided if things go bad.
