That was hilarious!
That scene reminds me of something someone said about American bathrooms compared to many other countries regarding the length of stall doors. In many parts of U.S. it wouldn't matter how quiet someone was in most bathrooms, you'd still see both sets of legs, even by just walking into the bathroom. If that was the case here, Minjae would likely have to do some awkward toliet acrobatics every time someone walked in to not be found out.
If someone has anxiety just ask them to go out to eat, don't ask for a date! xD
