Just checking

Have u ever wanted to press the emergency button just to make sure, just to see of anyone will pick up your mayday call. I mean what if they are no longer in business?! What if the service button is in need of service? I want to press it and say 'just checking.....thanx' but then, what if I tempt fate, what if the operator is nasty and traps me, what if....what if... I think I'll just leave it for now.... You never know.
