Bad customer service

I had a really bad experience in Penningtons Store at Dufferin Mall in Toronto, Ontario. Ladies working there don't possess any empathy and people skills. Today, I was almost hit by the driver that delivers goods to this store, and asked for details related to this man. In response the Store Assistant was laughing at me and suggested that maybe it was not an accident! I haven't met such rude person in my life. How unprofessional and cruel you have to be to behave like that... Penningtons should re-think their hiring strategies, if Store Manager Assistant acts like that, what we as customers can expect from the staff? Every company is nothing without its employees, therefore you need to choose them carefully because they are the reason of success or failure...
