This is why the bartender hates you.

17. Sorry, cant help you. Im posting from a phone.

Surely it can't be that hard to visualize. The glass is upside down on a coaster. Slide the glass off the coaster (it will leak a bit). The seal will be between the table and the glass. Slide the glass to the edge of the table until it extends far enough to drain into another glass.

I did it when I was fourteen years old to my art teacher. I had turned a glass full of water upside down using a piece of cardboard then removed the cardboard. She pulled me out of another class expecting me to have to clean up the mess. The solution didn't occur to me until that moment. If a fourtiin year old kid can figure it out, it can't be that hard.

If the glass is on a bar with z bullnose or a raised edge that solution won't work. But if you'll notice the glass is still on the coaster. All You have to do is reverse the process that put it there. The coaster is stiff enough for you to lean it and get a finger under it. And if the bar has a bullnose edge, just slide it far enough over to get a finger under it. You could even slide a knife under the coaster to lean it far enough to get a finger under it.

If you think I'm going to video something so simple and upload it to YouTube to prove it to you you have overrated yourself. I've given You at least three solutions, try it and see.
