Budget airline to charge to use the loo

Im thinking of traveling to Europe, just to fly RyanAir, and releave myself on the F/O's shoe as he or she is standing greeting passengers.
I dont like where airlines are going with fee's such as this (ie, less people using the "loo" means less lavatory service costs, less carry-on means faster boarding and deboarding). Have the airlines forgot how they stay in business? Thank God there are a few that still cater to the flying public and not their own bottom line and stockholders.
