You should so send his boss an email. I did that once for a customer and did not even get so much as a thank you. Then to make it even worse the same guy comes back a few months later asking for me to give him one of my links for a second Time Tank he did not even buy from us (I am guessing ebay seeing as it was already sized and he did not have links) then wanted to complain to my boss when I told him I couldn't because I all ready gave him all my extra parts the first time!
That's really messed up.
If that guy didn't want to thank you, then I'll say it.
Thank you, Brandon.
