Billiards has shared a roof with food and drink for a long time. In nineteenth-century America, taverns and hotels installed tables to keep guests in the building, and manufacturers such as Brunswick, founded in Cincinnati in 1845, built many of them.
That pairing lasted. Bars, restaurants and clubs still use pool tables to keep guests longer, and keeping those tables level and well clothed became a trade of its own: delivery, installation, refelting and repair.
