Under the 1830 Act any householder who paid rates could apply, with a one-off payment of two guineas (roughly equal in value to 168 today), to sell beer or cider in his home (usually the front parlour) and even to brew his own on his premises. The permission did not extend to the sale of spirits and fortified wines, and any beer house discovered selling those items was closed down and the owner heavily fined. Beer houses were not permitted to open on Sundays. The beer was usually served in jugs or dispensed directly from tapped wooden barrels on a table in the corner of the room. Often profits were so high the owners were able to buy the house next door to live in, turning every room in their former home into bars and lounges for customers.
What was forbidden from being sold in beer houses?
spirits and fortified wines

Another advantage, at least to some consumers, was the lack of any sort of anti-piracy technology. It was claimed that Macrovision's Copyguard protection could not be applied to LaserDisc, due to the format's design. The vertical blanking interval, where the Macrovision signal would be implemented, was also used for the internal timing on LaserDisc players, so test discs with Macrovision would not play at all. There was never a push to redesign the format despite the obvious potential for piracy due to its relatively small market share. The industry simply decided to engineer it into the DVD specification.
What protection could not be applied to LaserDiscs, making them prone to piracy?
Macrovision's Copyguard protection
