I don't think I would have been quite so nice.When I was younger I worked at Lowe's as a manager and I had a customer try to go over the counter at me over something completely ridiculous. Something about the price or what not and I said I had to go check on our shelves... I'll never forget it. I honestly think he may have been under the influence of something. I gave him the price and a discount, he was not happy when other customers came to my defense plus escorted him to his truck.
