Stop in for a cup of coffee

Does USPS allow it? Reminds me of a whackadoodle I was dealing with in Canada several years ago. I was selling some empty antique liquor bottles. They inquired if I would ship to them. I said I would check. In the meantime, this person started basically harassing me about not knowing the shipping rules. Then about how low my feedback was (over 500 all positive) Eventually telling me I had anger management issues. :wtf: I was just ignoring it and laughing more as their messages got more and more ridiculous. Lol
Yep, that is who I shipped through. I've also had beer shipped to me as well through them. Mind you I never told them what was in the package, took the risk of it breaking and not making it there.
