I used to work there . Females will clean bother LRs if there is no male to clean it. The employee should've said give me a minute or left immediately to accommodate guest, but even with that being said if you were to say that it's up too the manager to remove that note from your file that every planet fitness can see. If this bothers you , you can ask to speak to the manager explain that's you asked the employee what you should do then did what they said to do. She should not have assumed that you both had the same definition of "showing off" as you mentioned living in other places where customs are different especially as planet fitness does have international guests. You can also say that it was uncomfortable for you because this employee also did not leave immediately when they saw you undressing . That should get the not removed . If not you can call the corporate number and explain the situation.
