...and got my friend a free bottle of ($16) beer. As you can see, there are two (almost) identical bottles here. It's some raspberry beer that my friend was drinking. She bought a bottle ($16) and was having it mixed with Hoegaarten. (The drink is called a "Dirty Ho") ANYWAY... my friend had finished her bottle. At about that time, someone else started ordering Dirty Hos but did not purchase the whole bottle of the raspberry beer. SO the hot (but really dumb) bartender made their drink and then placed the nearly-full bottle just behind the bar, a few feet from my friend's empty bottle. SO my friend says "Dude! Switch those bottles!" I was like So I did. And the bartender never noticed, even as she continued to mix my friend's drinks with the mysteriously-full bottle of raspberry beer.
