Came in scheduled an oil change. Noticed the bright yellow sign that said "pay with cash get 3% off". I said to Dennis that's cool! I'll bring cash when I pay. He didn't acknowledge me said "we have a 5pm appt available". I said "okay. See ya at 5pm". Came back at 5pm and Dennis was standing behind the counter. Staring at me. Didn't say Hi, didn't ask me my name, didn't ask me what I was in for. I just looked back at him said "Melissa 5pm oil change." I handed him my keys and didn't say much else to me. The oil change was very fast and appreciated. Then Dennis waved me over. I said "I am paying in cash so I get that 3% off". He didn't say a word to me. Just said "$84.03 is your total" I tried handing him cash and he said "NO we are going to the counter". I walked up front well behind him and he was standing away from me at the other register. I paid not noticing I didn't get that discount. He said "did you hand her the car wash slip" and he walked away. No thank you for your business. Nothing. Went to my car and looked at the receipt and I did NOT get the discount. I walked back inside and asked the guy that checked me out if I missed it. He said no. Dennis was either having a bad day or just didn't like me. It's only 3% but if youre advertising it, give it to people. And maybe acknowledge your female customers existence. Unfortunately, I won't be back.
