You guys are, generally, I have found, intelligent human beings. Therefore, let me put this question to you:

 

If you come up to a lift, and it has a large notice on it saying ‘OUT OF ORDER, DO NOT USE’ do you,

 

a) Scream “noooo!” and beat your head against the closed doors while slowly sinking to your knees

b) Go find the stairs

c) Press the button (just in case) and get in the lift when the doors open.

 

( a, b or c? )
