Where is Bruce Willis when you need him?

A passer by saved us from an uncertain fate yesterday when the lift at the O2 arena broke down and dropped several inches. 8 of us including my pregnant daughter and her baby were trapped inside this sardine tin unable to contact the fire service by phone. The emergency button put us through to a distant town where the operator had never heard of 'Green Witch' let alone the O2 arena. 'Dont try to get out' he helpfully advised, 'we will get someone to you in no time'. It didnt happen, the temperature rose and we felt we were running out of air. Do lifts have air coming in and is it enough for 8 persons?
We had to try last resort measures ie bang on the doors shouting help. Our hero called the fire brigade before trying to get us out himself and prising the doors open.
