Round of drinks

[3] This practice is also customary in many parts of North America, especially in areas where people with cultural roots in Ireland and the UK predominate.

A notable exception was the UK State Management Scheme in which treating (i.e. buying a round) was forbidden, from July 1916 until June 1919.

Greaves' Rules is a set of etiquette guidelines common in the UK for buying rounds of drinks in English public houses.

The rules were first defined by William Greaves (April 1938 - November 2017), a London journalist of the defunct Today newspaper as a Saturday morning essay in the paper, based upon his long experience of pubs and rounds.

Copies of the rules soon appeared in many bars throughout the UK and are now known internationally as a representation of the spirit of drinking in a British pub.

Kate Fox, a social anthropologist came up with a similar idea in her book Watching the English, but concluded their rationale was the need to minimise the possibility of violence between drinking companions.
