"But hey, if you don't wanna talk, that's fine. Drink's still yours if you want it. If you don't, it doesn't matter" he shrugged. He took a sip of his own and looked at the glass as if it had caused offence to him somehow.
"Actually, if you don't drink it, I won't blame you..." he added. "But I'll go..." he said, turning on his heel to go. He was accustomed to people giving him attitude, especially at the bar. Less so in his other line of work.
