A Typical Workplace Conversation

Me; Morning.
Her; One ticket please.
Me; What sort of ticket?
Her; To use the underground.
Me; To travel to where?
Her; Baker Street.
Me; Do you want a single, a return or a one day travelcard?
Her; What's the difference?
Me; A single is one journey, a return is two journeys and a travelcard is valid all day.
Her; Yes o.k.
Me; So which one?
Her; I've got to go there, then come back.
Me; That's a return then.
Her; Isn't a travelcard cheaper?
Me; Only after 9:30am.
Her; Isn't it 9:30 yet?
Me; It will be by the time we finish this conversation.
Her; What time is it now?
Me; Ten past nine.
Her; Oh no. I can't wait that long, I'll just have a single.
Me; Three pounds please.
