This is another project that I am actually re-doing right now, this is going to be a short story in a collection.
This is about a woman on either a vacation or a business trip who is in the middle of taking a shower when the fire alarm goes off in her hotel. She grabs a towel and bolts from her room to the first elevator she sees which takes her to a service corridor in the basement. She then gets locked in the corridor and loses her towel.
A few minutes later another hotel guest in the same situation arrives and also gets stuck after trying to catch the elevator. Things go from there.
