Race to the top

When you return from a teaching appointment with 4 missionaries and an 88 year old ward missionary and her dog who lives on the 7th floor of this apartment building and the elevator only squeezes in 4 (if you hold your breath), what do you do?


Of course a gentleman doesn't send the 88 year old and her dog up the stairs.


However, it turns out that 7 floors is really 9 since we started on -1 and the ground floor is 0.


Can you tell who took the elevator? I almost beat them to the top.
