Have you been to a Gym? They are expensive aren't they? And, they tend to keep 'bank hours' where they are only open between 10am and 3pm Mon to Fri and closed at any other time. This is in order to keep the equipment in pristine condition for further promotional material to attract more people to join the gym.
Now, I have noticied that our enterprising public transport system has discovered a new way to increase revenue to pay for the desperately needed rail improvement works. By closing stations, turning off escalators and disabling lifts the system ensures a healthy workout for all privileged patrons of the system. With honest marketing a 50% increase in the cost of the fare is justified. They have installed saunas, step-aerobic systems, weight training rooms and general cross-training environments.
