This is not a joke. Mere chit-chat. I spoke to the barman concerned and he told me that he could not serve Shakespeare because it was against the law to serve anyone under the influence, and he was clearly as Tight As Andronicus.
Had he gone in the day before, the 5th Jan, he would have been OK, but he went in on Twelfth Night. He also hadn't heard of the smoking ban, so asked for a Hamlet.
What's more, the bit of stuff he was with started working her ticket and refused to leave the premises when asked so the barman had to call for assistance in removing her, saying to his colleague,"Julius, Seize her!"
