McDonald's review: Customer service order issue

yesterday at 6:05 a.m. we went to the drive thru at 103 Hammett Bridge Rd in Greer SC to the McDonalds we ordered breakfast and a lg coffee this is a busy drive thru. They had a new person evidentially running drive thru she looked totally overwhelmed. We got to the window my husband ordered a chicken biscuit add cheese add egg, We got home which is 3 minutes away he went to get his coffee out of the cup holder and where they are in such a hurry they didnt have the lid snapped down and hot coffee poured all over his lap and leg he was wearing shorts. There hurried behavior could have caused serious injury. I called the manager and told her what happened she said she would replace my order or refund my money. I guess she thought she put me on hold, because she preceded to talk to her cashiers on her headset and stated that supposedly they hadnt put the lid on the coffee and supposedly it spilled on my husbands lap. I requested my money back she said ok shed leave the info with the night manager i could take my receipt up there and ask for Kinsey. When my husband got home from worked we went up there. I asked the girl at the counter if i could speak with Kinsey only to find out she was the manager i spoke with earlier. She got the night mamager and started telling her about the conversation with the morning manager only to keep getting interupted numerous times by the girl at the counter, Everytime i started to speak she would interupt me again. I am 61 yrs old and worked in the food industry for years we were never supposed to talk to anyon like that that is very rude and very bad customer service . Well she wouldnt let me get a word in so i finally told them to keep my money and that we wouldnt be back where she then said ok and have a good night really loud. My husband could have been seriously injured and they only thing they were going to do was offer a replacement cup of coffee. I will go elsewhere from now on where people arent rude and listen to customers.
