Ordered on mobile app 15 minutes b4 I arrived. Food not ready. I get it and park. My breakfast sandwich not have extra bacon i paid for. I went back inside to just get the extra bacon. Young man at counter says I got you. Had an WHOLE NEW SANDWICH made for me and told me to keep one that was not correct. Just awesome. I ate SANDWICH not correct and gave new correct sandwich to my coworker. Both of us had good morning because of that young man.!! Just awesome. Manager walked by while I was waiting an ask if I needed help. I said no young man was helping me. What a great staff!!! Hwy 141 and 30 McDonald's Missouri. Be kind and show them love and patience ❤️

Came here ordered two burgers no onions no mustard get home to find one burger completely destroyed and just throw together I think oh well no big deal I’m hungry I take one bite and guess what’s under the two extra pieces of cheese onions luckily this isn’t an allergy more of a preference but maybe you should have your people pay a little more attention before you get sued for causing an allergic reaction Edit: how do you mess up both burgers and try to hide it in between the meat and cheese next time
