After "well-behaved" Barclays beer event, some vomit on sidewalks nearby

From The Daily Meal, Tapped Brings Lots of Beer, Thousands of People to Barclays Center for Its First Beer Event:

On Sunday afternoon, thousands of thirsty beer lovers packed into the Barclays Center, located on the northern end of Brooklyn’s Park Slope neighborhood, for the sports and music venue’s first major beer event, called Tapped. During two epic sessions, nearly 30 different breweries poured more than 100 beers.
The beer stations were primarily set up on the arena’s floor, which became packed shortly after the doors opened, and a handful of stations were set up on either side of the arena’s concourse as well. Even though it was incredibly crowded, with some guests waiting several minutes on line between pours, everyone was well-behaved and seemed to really be enjoying themselves.
...Overall it’s hard not to consider the event an overwhelming success; big crowds means that it sold well.

First, "big crowds" can also mean it sold well after discounting. More importantly, however well-behaved people were inside, a neighbor tells me there was periodic visible vomit on sidewalks nearby.
