Hopefully in addition to serious compensation, the FAs handled this in a manner worthy of your status, mbwmbw. Surely, you demanded when you needed to use the facilities, all passengers in the back were to clear the aisles, sit in their seats and look away from the middle of the plane. It goes without saying, prior to your promenade to the back, the lav was scrubbed from top to bottom, lest there be any chance of your getting ill from having to use the same lav as "them."
