Suddenly everything stops

Imagine that you rush into your hotel room with you hands full and drop your keycard to the floor when trying to shovel it into the main light switch while the door is closing behind you.

Suddenly you get a feeling that there's no rush and the best thing to do is crawl on the floor in total blackness.
-Further you can't avoid thinking that this was not considered, when the brilliant idea of key card operating main switch was introduced to hotel businnes.
