- DKDaniel kimFeb 26, 20265.0My favorite over 29yrs))
- SFsummer fuFeb 22, 20261.0I went through the drive-thru around 3:10 PM on 2/22. I ordered two Happy Meals, one McCrispy medium combo, and a 10-piece Chicken McNuggets. When I got home, I found a long hair inside one of my son's Happy Meal chicken nuggets. This is extremely gross and unacceptable, especially since it was for my child. I did not take the receipt, but I paid at the drive-thru around that time. Please advise how this can be resolved.
