If you have spent some time in dive bars, and even some "regular" bars, you have probably at some point experienced a bar fight. It can be cool the first time you see one - there is always that initial 'Whoa, dude! Did you see that?' factor. But, after a while you start to get annoyed and almost want to join in just to punch the guy who started the whole thing in the first place because now your drink is all over your shirt, your buddy who was innocently standing there got punched, and the bar has been shut down for the night due to the police being called to break it up and shut it down. But that's nothing...
Here is a list from Mandatory of the most dangerous bars in the world. Think you've seen a bar fight? Think again... unless you've been to one of these bars.
