Three engineers and three CAs are traveling by train to a conference. At the station, each of the three engineers buys a ticket while the three CAs buy only one ticket.
“How can the three of you travel on one ticket?” asks an engineer.
“Watch and you’ll see,” answers an CA.
After boarding the train ,the engineers take their respective seats while all three CAs cram into the restroom and squeeze the door closed behind them.
When the conductor comes around collecting tickets, he knocks on the restroom door and says, “Ticket, please.” The door opens a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on.
The engineers are impressed with this clever idea. One the way home from the conference, they decide to copy the CAs’ technique. At the station, they buy a single ticket for their return trip. To their astonishment, the CAs don’t buy a ticket at all!
“How the hell are you going to pull this off?” asks an engineer.
“Watch and you’ll see,” answers a CA.
They board the train. The three engineers cram into one restroom and the three CAs cram into the other restroom.
Shortly after the train departs, one of the CAs leaves his restroom and knocks on the other restroom door. “Ticket, please!”
