Yeah, you can blame me for this one (by Alan B. Combs).

Generally, a bartender’s life is a happy one. People pay top dollar for the unique services they bring, and by far, the result is an increase in joy. The most joyous occasions are those in which the bartender joins the patrons in a libation and buys a round for the house. That is when our benefactor finds friends galore, all of whom are hoping to share in the bounty.

However, when closing time rolls around and it is time to clean the place up, then, all those previous friends evaporate. Then, it is that the bartender is left alone to prepare the premises for the morrow. Truly, it is said, “Quaff and the world quaffs with you; sweep and you sweep alone.”
