I asked the train bartender if she knew where i could... "smoke?" she interjected. "No, find a plug to recharge my laptop!" i said. She didn't know and turned towards her coworker for help. The dude seemed in a rather merry mood and jokingly answered me with "in my pocket? Maybe in my underpants?". "In your behind?" i added.
The answer is: in 1st class.
