Hot air

"What do you mean by that?"

"I'm sorry, I was just saying that sometimes if one carriage is cold, it doesn't mean the entire train is without heating."

"You mean the driver's nice and warm in his cab I suppose?"

"No, sometimes carriages either side have heat, even if the one you're in doesn't."

"You must think me a fool: there is a continuous pipe which supplies heating to all carriages, a bit like the communications chord."

"I wish someone would pull yours!"

"I'm sorry. What did you say? Why are you whispering? Are you simple as well as stupid?"

"Pardon me for just trying to help."

"Well you didn't help did you? It's still cold in here. Why don't you call the Guard if you want to do something useful?"

"They don't have Guards on these trains anymore."

"Of course they do. Whoever heard of a train without a Guard - akin to a pantry without a housekeeper. Ask one of these people if you're unable to locate the Guard yourself? Why are they all piling in here I wonder?"

"That's better. I thought I'd be baked alive in there..."

"Where have you all come from; did the Guard re-locate you?"

"We were in the next carriage which had the heating full-on. We needed to get out. All that hot air made us feel quite sick."
