"Incident at Metropolitan Market Queen Anne, Seattle"

I was moving up the right side of the aisle, slowly hobbling with an inflexible leg and a cane as he walked straight toward me. He had ample time to move out of the way but chose to block the path of this disabled elder then accused me of physical aggression (which isn't possible) after he bumped into my cane arm while trying to squeeze between me and the shelving. It was a bizarre move, especially since the rest of the aisle was otherwise vacant. From behind me I hear "why did you hit me" from the 20 something guard to this 76-year-old. Degenerative bone disease made this a dangerous move by him if I had lost my balance. Minutes later he initiated another minor incident which is too ludicrous to describe. After checking out, I couldn't let it go and confronted him. Denial. Tried to make up a story to justify his behavior.
