Free bugs included in your Meal only at Mc Donald's

Last Night we bought food from Mc Donald's Carletonville. After I almost finished my chips I noticed something at the bottom of the package. When I had a closer look I found 2 bugs, that was dead inside the package. I was soooo disgusted. I don't even want to know how the kitchen looks on the inside if they didn't notice this. Is it really as clean as we think? My husband and I didn't even finish our meals as we were feeling sick after this. I don't want any free meals or vouchers, this place needs inspection from the department of health, there is no way I am going back there to buy any more meals. It's disgusting
