Halfy's Sealed Knot story reminded me...
(Note: this doesn't actually take place *in* a pub, but it involves the service of alcohol so I'll post it anyway.)

When I was a kid my family lived in Britain, and the parents used to take us out on educational field trips of a weekend to various sites of historical interest. One weekend during summer, we went to see a reenactment of some English Civil War battle. It was a fairly hot day (well, for England, anyway) and the soldiers, dressed as they were in full historical regalia and lugging around pikes, were working up a mighty thirst.

When the battle was over, the exhausted warriors staggered off the field to where tankards of beer were being handed out by a guy dressed as a wizard (I never knew that either side in the Civil War utilised wizards, but I guess you learn something every day). One fatigued Roundhead soldier, dripping with sweat, grabbed a brimming mug of ale from the tray, and with a relieved cry of "Ah, beer!" took an almighty swig.

Or at least he intended to. However, while he had laid down his pike upon quitting the battlefield, he had neglected to remove his helmet. His visored helmet.

The mug met the visor with a clang and stopped dead, while in accordance with Newton, the beer kept going, completely drenching him in booze to the amusement of all present.

So there you have it. Despite the fact that it finished over 350 years ago, the English Civil War continues to claim victims.
