What is Jewish Lemonade?
1.
A free drink created by penny pinching Jews who don't want to have to pony up for a beverage when they eat out.
It is done by ordering an ice water with lemon, squeezing the lemon juice into the icewater, then using sweet-n-low packets from the sugar rack on the table to sweeten the "Lemonade". Free beverage! Oy vey!
