Happy Hour is the term given to a period of time (often longer than an hour) where pubs...
- reduce the price of many of their alcoholic beverages
- run special offers like buy 5, get 5 free
...in an attempt to drum up trade during quiet times or to entice drinkers to their hostelry.
Currently our no fun government is trying to outlaw the practice as it contributes to public disorder and drunkenness ... even though this is the same government that pushed through 24 hour opening!
Also, in many Messes around the world, a period of time on Friday when all the livers-in arrive in the bar to be met with screaming kids and senior officers entertaining friends and family. To be avoided!
