On New Year's Eve my mom was meeting me at costco. As she approached a parking spot in her tiny Honda Fit there was a cart left in the spot and my mom bumped it with her car. The cart shot forward hitting the grill of the car in the spot in front her. She got out of her car checked for damage and pushed the cart to the cart corral. A woman who witnessed this began screaming at my 72 yr old mother saying "I saw what you did you stupid B@#$& , you better call the cops or I will" my mother explained to her that she forgot her cell at home and was just putting the cart away. The woman then tried to get an employee involved who was collecting carts. She continued to swear and berate my mother even though my mom was writing her info down for the owner of the car. My mom was pretty shaken up and asked her to stop but she would not. The owner of the car arrived and was a lovely older gentleman. My mom explained what happened while the woman continue to call my mom names and yell at her. The kind gentleman told the woman to stop and assessed the damage which was minimal and apologized to my mother for that rude woman's behaviour. I would like to call out that rude woman, your behaviour was uncalled for and rude and disrespectful. Shame on you. To the owner of the car thank you for being kind and understanding to my mother who was feeling terrible and quite shaken by this incident.
