Rude security

I was unfortunate enough to choose the Pick N Pay in Elgin Mall for a couple of quick items. Unfortunately, the staff there have had no training in how to deal with injured people. The rude security could not understand that I can not control a large trolley with a arm out of action. He felt that it was perfectly OK to push me out of the way and then added insult to the assault when he told me to stand outside the store. You guys can take your groceries and stick it where the sun don't shine. This is not the first time I have had a bad experience there, but it will definitely be the last time.
