Yes, super grumpy, even better.
My last visit was in December of last year when I presented the ACG free drinks coupon. He came running over when he saw it, and barked at us, "this is the last year for those, they aren't good next year", as if there was a problem. So I said, well this is still good now, right? And of course it was. No hello, or how are you today, what would you like to drink. Just typical of him. You'd think he'd find some other line of work.
