If you're unsure how this mystical machine works, basically, it's a drink machine that can dispense anything that can exist in a liquid form, including some rather esoteric things, like liquids that induce certain emotions. In SCP Containment Breach, you can order "call of duty" and get a drink that "tastes like dubstep and ur mom." It will always appear in a 12 oz paper cup.
Here's how this thread works: You've inserted your money and nobody's around to stop you from ordering whatever you want. Enter your order in quotes, the person after you describes what the drink does, even what it looks like if they care to.
Example:
OP orders "can of whoop-ass"
Responder: "The drink burns slightly going down, giving you an incredible urge to punch everything."
Very little is off-limits. Go nuts!
For starters, I order "Estus".
