Relaxing between sessions:
This is however a fantastic time to have a good look for unusual beers (and to spot which beers have been flying out and are likely to run out shortly!). The angle of the cask - known as the "stoop" - is often a good indicator of how much beer is left inside. This should only ever be done by an experienced cellarman - stooping too early will churn up the sediment and can render the beer undrinkable (as can tilting the cask by hand, no matter how well-intentioned the motives are!).
We did have the unusual phenomenon of a queue forming before 4pm - possibly in reaction to the 100 first-come, first-served tickets for sale on the door. Friday night is our flagship session, often selling out three or four weeks beforehand, so a busy night is expected. This is also the session I often describe to people as being more comfortable behind the bar than in front of it, as we have more space!
