Gym Ninja

The hotel has a 24/7 gym - but it's really freaky going down there at 4.30am. Waiting for the lift (I get the irony) it was so quiet that I expected to see Freddy Krueger when the doors opened.

Assume the Ninja position and then hope you don't give the cleaning staff heart failure when the doors open and they are confronted by a crouching wild-haired middle-aged woman.
