why "sweet´n´lo"?
Hi guys. I was watching this "Friends" tv show. And somebody says "sweet´n'lo" when ask for a coffee (de-caff).
So, I understand the meaning. But, imagine that you are in a cefeteria and you ask for a coffee, then you are talking to your Friends and the waiter give you that coffee and you ask: sweet´n´lo?...Why would you say that?

tHANKSSSSSSSS :D

https://en.wikipedia.org/wiki/Sweet%27n_Low
The name "Sweet'n Low" derives from an 1863 song by Sir Joseph Barnby, which took both its title and lyrics from an Alfred Lord Tennyson poem, entitled The Princess: Sweet and Low.[2]

To be clear,  Sweet 'N Low is not coffee.

Answer

"Sweet 'N Low" is the name of an artificial sweetener.
