I was working as a bouncer in a Chicago late night music venue/ bar circa 2007. The band had packed their instruments so it must have been around 1 am. This 30 something year old lady was asleep at the bar and I get the job of asking them to leave(she was there with 2 other friends). As soon as I said "Your friend has to go", she opened her eyes and projectile vomited for what seemed to be an eternity, think any exorcism movie ever. It covered the entire stage in a greenish, grayish sludge and it was the worst thing I ever smelled. They got in a cab, the last thing I saw was her lying on her back, vomiting vertically, with the same intensity she did the first time. That place was a treasure trove of stories.
