From within the stall, Jon heard someone coming into the room. What would someone say if they found him (her) in the men's restroom? He didn't think he'd get arrested, but he sure would be in trouble.
One of the stall doors opened and Jon heard someone urinating. He exhaled a sigh of relief. But then the restroom door opened again. This time two people entered. Jon knew because they were talking to each other.
Jon heard their footsteps coming closer and closer. What if they found him?
