Holidays Bring Out the Best in People

Does anyone have any stories of how holidays and holiday shopping just seem to bring out the best in people? Yesterday, I was in an aisle working topstock. Only one customer, a woman, was shopping in that aisle. Suddenly, another customer, a middle-aged women on her cell phone comes barreling through. Without missing a beat she angrily exclaims "That cart is in way" and then keeps going, continuing her phone conversation as if nothing happened. The customer that was in the aisle shopping and I looked at each other in shock because we really didn't know who she was talking to. (The angry cell phone woman went around both the other customer's shopping cart and my topstock cart as she sped through the aisle.) I just said to the shopping customer, "I don't know which one of us she was talking to, but I would've gladly moved my cart for her if she needed something that I was blocking." The other customer just sort of rolled her eyes and said some "Some people".

Does anyone else have any fun stories of irritable and/or rude customers?
