I make a drink for on-the-go situations (like concerts in the park). I get plastic bottles of Lipton Green Tea, Citrus. I open the bottles and drink (or pour out) about 1/3rd of the bottle. I then pour vodka in to fill. Totally inconspicuous.
My gf named them A Cry For Help.
I actually like a “Gin Buck”, especially in the summer. As you might imagine, it’s 2oz of your favorite Gin, plus Ginger Beer and lime juice + wedge.
I drink it out of a Collins glass, not a copper mug.
The Ginger Beer matters a lot. I like Fever Tree, Bundaberg is good too.
