My friends are taking the Amtrak from San Diego to Burbank.
First, we board the train and sit at a table on the second floor of the train. All is well until we get hungry...
There is a cafe almost directly below us, and our table is right next to the stairs. We walk down the stairs and are instantly greeted by about a dozen 25-40 year old men, drinks in their hands, and a slurred array of lines such as "LADIESSS" "Heyy, baby" and "You know, 16 is the legal drinking age in Europe...!"
By avoiding eye contact, we managed to escape to our seats.
A bit later, some of the drunk guys come up from the cafe and stand at the top of the stairs, right next to our seats. They start playing (bad) music, and one sets his beer on our table. We wait until they have finished their song and I ask them, semi-polite and semi-firm, to please turn down the music. They apoligize sarcastically, laughing like...drunks. We remind them that they aren't the only ones on the train, and they finally turn off the music.
Suddenly, we hear yelling and crashes by the stairs, where, according to later accounts, one man accidentally stepped on another's Cubs hat, resulting in a 6 on 2 fist fight. We hear punches being thrown, a girl screaming, more cussing than Superbad, and an Amtrak worker being put on hold by the police.
This goes on for a good 10-15 minutes. A call is then sent throughout the train for anyone on the train with medical training, and we are delayed an hour.
Meanwhile, another intoxicated man has invited himself to sit at our table. He smells.
I don't think the Amtrak can do anything about stupid people, but they can control how much alcohol they sell to customers. These guys were very drunk, very loud, and very rowdy before any violence.
