While at a restaurant tonight, the bartender made the PERFECT Gibson. 

I asked the waitress for a Gin Martini, shaken. 

She offered onions, I said yes.

The Bartender filled in the blanks.

So, I got up from our table, walked to the bar, complimented the Bartender, and tipped him cash directly.

When you have an excellent cocktail while seated, please do the same.

Cheers!
