in japan as most of us may know there are cosplay cafes around there. 

i recently found out about this new one called: Sergeant cafe. 

supposedly it's a military themed cosplay cafe where you walk in as a new recruit and the waiters are your military drill instructors.

there is even a warning that says this: “once you join the army (enter the café), you must obey whatever sergeants (waitresses) say,” “when you order food or drink, you order to a senior officer, so you have to say ‘Sir!’ first”. There were 2 courses: Hard Course (1F) and Soft Course (2F). 

On the 1st floor (Hard Course), former U.S. Marine Corps scolded trainees (customers), let them do push-ups or jump. The former officer said “this is nothing- you have to do such things every single day in the real Boot Camp.”
