disgusting behaviour

My 75yr old father went into the shop to get pricing on printing... the staff member grabbed my dads work and started shouting at him. He asked her to not damage his pages and she swore at him and when he told her to behave she grabbed his work and ran to the owner who came up to my father, shouting at him and told him to get the F*#K out of his ship and never set foot in it again. I was absolutely disgusted at this behaviour and left with my father. I will never set foot in there again.
