If you want to get more people to use the stairs versus an escalator, you can:
A) Remove the escalator (although that will hurt people who are not good at climbing stairs)
B) Pass a law that only disabled people can use the escalator (hard to enforce)
C) Charge a toll for the escalator (easy enough, but expensive to implement & maintain, plus it hurts the disabled who really need the escalator)
D) Make climbing the stairs interesting or kind of fun.
That was pretty cool.
Why would I care which people use? Be a fat bastard if you want.
This was in Sweden, which has Nationalized Health Care, so fat bastards cost the state more.
At work we were joking that they should install a weight sensor on the escalator, and anyone who trips the sensor will cause the escalator to emit sounds of strained materials & machinery, maybe even emit a bit of smoke, slow down noticably, &/or declare that it is “Engaging auxillary power systems”. While the stairs could offer words of encouragement.
