Nice and simple your one Eskimo... the guy is short, can only reach that button on the way back up. So has to walk the rest of the way. NOW if it had been raining and he had an umbrella, he could take the lift all the way up
As for my riddle...
The person who makes it, doesn't want it,
The person who buys it, doesn't use it,
The person who uses it, doesn't know it.
