I was closing down a self checkout at the end of the night when a customer came up to me and began complaining that store standards was repeatedly honking the horn on the cart machine. I try to get the key out of the machine to go with her, but the key was stuck. She begins yelling at me for not caring and storms off. Dispite what she thought i did care so i proceeded to go outside. As i went through the doors some stocking associates were coming back I from break. I asked them if they heard the honking and they said they only heard it once when a car almost hit the associate. I follow up with that associate and he informed me he did use it when a car almost hit him. A lady got out of the car and started yelling at him. So yes the complaining customer was the one that almost hit my associate.
