Mass killing averted on train

[Chacal Profile Website]

So I'm on the train today on a 3-hour trip, reading a boring document with undeserved "Restricted" stamps all over it and around page 72 I think "Damn, I'd kill for a Guinness". Suddenly this guy comes by pushing a cart, and there's a black, tall can on it. Minutes later, I'm having an ice-cold Guinness and a can of Pringles and life is not so bad after all!
