Don - "Not that I eat at McDonald's all that often, but if I'm out and in search of a rest room, I can usually rely on McDonald's."
That's call a 'McDump'... entering a fast food restaurant with the sole purpose of using the facilities. When I worked in a library near a McD's, we would always advise our disabled customers to go to their bathrooms rather than use ours as - you guessed it - it had an inward opening door that even able bodied people had trouble with. If you pushed it hard enough, it wedged on the sink (wash basin).
