I'll drink to that
Roger Scruton says
"The practice of buying rounds in the pub is one of the great cultural achievements of the English. It enables people with little money of their own to make generous gestures, without the risk of being ruined by them. It enables each person to distinguish himself from his neighbours and to portray his individuality in his choice of drink, and it causes affection progressively to mount in the circle of drinkers, by giving each in turn the character of a warm and hospitable friend."
