The staff at the changing room entrance had a terrible attitude.

My two daughters wanted to enter the changing room together, but the staff stopped them and spoke to them in a very rude manner, saying, 'You're old enough—you don’t need anyone to accompany you.' However, I didn’t see any sign at the entrance prohibiting two girls from entering together. Even if there is such a rule, they should have explained it politely instead of treating my daughters so harshly. Your service attitude needs improvement.
