Maybe they have a McWipe in the bathroom.  
You know how McDonalds have the McWash for your hands?  I kept putting a requisition for a McWipe (for your ar5e obviously) in the McDonalds suggestion box, but so far, no response.
Maybe they have a prototype McWipe in the BB bathroom.  Testing it out on Glynn before they install them in MickeyD's worldwide.
Just a thought.
