I got in a race with the bar staff at a bar where one of our clients/suppliers (can't remember) was picking up the tab. The first mojito I ordered took ages, so I told the waitress to keep bringing them back until hadn't drunk the previous one.
The whole night is pretty blurry, but reports vary from twelve to seventeen, in around a five minute window. I do remember that the bar staff were constantly making them and lining them up on the bar for her, and she'd walk over, pick up the empty glass, hand me the new one and walk back to the bar while I downed the one she'd just gave me, at which point she'd be on her way back with a new one.
It didn't even get me that drunk - they weren't exactly overflowing with rum - but the amount of citric acid I was consuming was causing some serious heartburn
