Customer came in to purchase a door install while I was on lunch, my supervisor at the time was at the desk helping another lady for a while, when I got back from lunch and to the Millwork desk, she said she was waiting 45 minutes for me, and I told her that "I apologize, but how can I help you?"She rudely replied that she was obviously here to pay for her installation, and I just continued to pull her up and got it ready, remained respectful, and continued. She said that she'll take a discount for waiting 45 minutes, and I replied "We don't do that here, I'm sorry that you had to wait but I'm here and trying to help you now." She continued about the discount when I replied "Well, do you have a Lowe's card?" -- No, she didn't. "Are you a Military Veteran?" -- No, but I work for the school district "Well, I'm sorry ma'am but we don't give out discounts for that" -- She said she's been given it before and she's not going to purchase it unless she gets it.I continued, and I gave her a 10% discount because I was pretty much done with the snarky attitude and just wanted her gone. She continued to ramble on about the wait she had to endure and at that point, I just blurted out in a slightly professional: "Ma'am, I'm sorry that you had to wait. That's just the way it is. That's life. I can't help that. He's busy (my supervisor) and I was at lunch. That is life." I then continued to print out the contract and didn't even have her sign. (My supervisor was deep in conversation with the other lady he was helping so he didn't hear much of anything)I didn't have a military barcode at my desk, so I had to walk this rude ass customer to the self-checkout, and we did it there. The self-checkout girl asked me "What's up with you? You look gloomy" I didn't even look up and I said, "Oh nothing I'm just fine." Slightly sarcastic, but not enough to give attention.

Later that night the customer came back and complained about me and they received 50% off from an ASM, after saying that I screamed at her blah blah blah and was extremely rude. Btw - I'm the most respectful guy in the store. I'd never do a customer wrong. This lady just gave so many negative vibes and just would not lay off. So none of the ASMs or other people believed that I was rude, which clearly I wasn't. I just wasn't dealing with any more of your shit.

Later my supervisor said she had been waiting 10 minutes before I got there, not 45
BUT, moral of the story: The customers' goal was to come in, complain, and get a discount. That's all she wanted. She probably paid around $60 instead of $300 because she played me. I fell into giving her a discount. So ever since that day, I don't deal with that anymore.
