OK. So I'm at Bar tonight and this guy rings the naval bell which adorms the local bar where you purchase drinks. It is similar I have been told to the type of artefacts which adorn many licensed premises across the world eg bells, bollards from sunken ships etc, usually in memory of those who have died serving their country. Anyway, this almighty argument broke out between these two mates of mine. One said you had to buy (shout) drinks for those people who were actually at the bar and who were addressing the bartender and ordering drinks, while the other friend said, no! you actually have to buy drinks for everyone on the premises at the time [potentially the difference between 10 people and 200). Hardly scientific I know, and I apologise in advance, but it certainly took my interest and I'd be very interested to hear from those in the know. Cheers!
