redeem their drinks during the lock-in so no drinks are technically sold after closing time. The origin of the British lock-in was a reaction to 1915 changes in the licensing laws in England and Wales, which curtailed opening hours to stop factory workers from turning up drunk and harming the war effort. From then until the start of the 21st century, UK licensing laws changed very little, retaining these comparatively early closing times. The tradition of the lock-in therefore remained. Since the implementation of the Licensing Act 2003, premises in England and Wales may apply to extend their opening hours beyond 11 pm, allowing round-the-clock drinking and removing much of the need for lock-ins. Since the smoking ban, some establishments operated a lock-in during which the remaining patrons could smoke without repercussions but, unlike drinking lock-ins, allowing smoking in a pub was still a prosecutable offence. Smoking bans Concerns about the effects of cigarette smoke inhalation first surfaced in the 1950s and ultimately led many countries to ban or restrict smoking in specific settings, such as pubs and restaurants. Early in 2004, the Republic of Ireland became the first country in the world to ban smoking in all enclosed public areas. Scotland was the first UK nation to introduce a ban on indoor smoking in March 2006, followed by the rest of the UK in 2007. Australia introduced a similar ban in 2006 and now has some of the world's toughest anti-smoking laws, with some territories having also banned smoking in outside public areas. Some publicans raised concerns, prior to the implementation of restrictions, that a smoking ban would have a negative impact on sales. The impact of the ban was mixed with some pubs suffering declining sales, and others seeing an increase, particularly in food sales. Architecture Saloon or lounge By the end of the 18th century, a new room in the pub was established: the saloon. Beer establishments had always provided entertainment of some sort—singing, gaming or sport. Balls Pond Road in Islington was named after an establishment run by a Mr. Ball that had a duck pond at the rear, where drinkers could, for a fee, go out and take a potshot at the ducks. More common, however, was a card room or a billiards room. The saloon was a room where, for an admission fee or a higher price of drinks, singing, dancing, drama, or comedy
