A couple of years ago, I worked in an office, where there were 3 washrooms: Boys, Unisex, Girls. So, people might go to the Unisex one if the other was occupied. One day, as I was coming out from the Unisex washroom, almost bumped into another MBA co-op student, who shouted out:
"Wow, you go to the VIP washroom!!!"
Then, you realize that you got to respect the MBA people's talents and expertise ...
