4. It was the accepted practice in Babylon 4,000 years ago that for a month after the wedding, the bride’s father would supply his son-in-law with all the mead he could drink.

5. In English pubs, ale is ordered by pints and quarts…
So in old England , when customers got unruly, the bartender would yell at them ‘Mind your pints and quarts, and settle down.’

7. In 1696, William III of England introduced a property tax that required those living in houses with more than six windows to pay a levy. In order to avoid the tax, house owners would brick up all windows except six. (The Window Tax lasted until 1851, and older houses with bricked-up windows are still a common sight in the U.K.) As the bricked-up windows prevented some rooms from receiving any sunlight, the tax was referred to as “daylight robbery”!
Now, there you have the origin of these phrases.
