sign it

after doubting for a while finally you sign up and leave the contract over the desk and walk towards the elevator
as you walk you try to find the receptionist... (you don't even know her name) but with no success she's not here yet
so once you arrive you call the elevator and enter with the doors getting closed behind you inmediately
once you enter in the elevator you turn around towards the button for going up when you see... that there are several floors
you don't know which is the floor you're supposed to go... the receptionist only said to take the elevator and what to do once you're into the right floor...
maybe you should go back and try to discover the right floor... but as you try to open the doors or press the 0 floor the doors doesn't open... a key is needed for that floor... but not for the upper ones...
that's weird... but you've ****... which floor do you go to?
