How to find a vacant restroom...

...at the place where I work.

 

 PLAN A

1. Make your way to the bottom floor down the stairs, checking each floor for a vacant restroom. Should you find one, use it.
2. When you reach ground floor and no vacant restroom was available take the lift to the top floor and repeat Step 1.

PLAN B

1.  Tell the intern to find you a vacant restroom and let him "hold" it for you while he WhatsApp you and tell you which floor to proceed to.
2. Don't let the intern leave the building.
