One of them might have ended up liking me just a bit too much...
One of them came up to me shyly one day and gave me the above made out of copper wires. He was sweet and innocent enough about the whole thing that it didn't freak me out. It is now like a trophy of sorts I proudly show off in the office. I can't get the Purchase Order (yet) but at least I have my name made out in copper wires by my customer. No other salesperson in the office could say the same for themselves.
