You Irk Me Things That Irk or Annoy Us

I am a courteous person and I almost always move out of the way when people say "Excuse Me", but when they say excuse me and just keep walking in your direction and then grunt at you when you don't jump out of the way and they almost knock you over it just Irks me! Yesterday in Sears and I was trying on shoes and the aisles were very narrow. I had just finished putting away the shoes I was trying on and was returning my shoes to my feet and an older lady behind me said excuse me and continued walking as though she was going to walk into me and then she grunted when I didn't move. I would gladly move out of the way but I need to be in the position where I can safely do so. I was bending over and if I moved I would have tripped and fallen on my face. As I finally moved I turned around and she gave me a dirty look. So I decided to tell her "if you waited one minute I would have moved out of the way safely I was putting my shoes on and couldn't move without tripping". She then replied "Well I said Excuse Me!". Really I didn't realize that it meant that if you say excuse me it means that no matter what and no matter if it would cause you to trip I had to move. I always let other people go when they need to get by, I always am courteous but in this case I think she really should have been patient and waited a moment. All she was doing was browsing the shoe aisle she was not in a shoe emergency. Come on people be patient and wait a minute when you say "Excuse Me."
