Pull the damn cart out of the aisle and back to the galley when there's a bathroom emergency, lazy Delta FA's, and let the guy through. I am sorry to hear about the guy being ARRESTED AND STUCK IN JAIL FOR TWO DAYS, but I think the FA's who refused to give him passage to the toilets in the back of the plane should be investigated, reprimanded and retrained.

The whole operation (pull back to the galley, let the guy by, return to original spot and continue service) might have taken 30 seconds on a 3-hour flight. Inexcusable.
