I had to go to a pharmacy today to buy somewhat personal/embarassing items. I went to the closest pharmacy, but the shelf I needed was right beside the pharmacy counter with a long lineup of people and an elderly person had blocked the shelf by parking his motorized scooter in front. When I tried to get closer, another guy squeezed by me and hit me in the shoulder with a shopping basket. I got the hell out of that store and drove to another pharmacy. Is this a personality type behaviour, or would any frustrated person do the same?
