McDonald’s complaint: To much ice cream?????

I pulled in the drive threw and ordered a happy meal and 6 ice cream cones and 2 cups of ice cream for the children i had at my house and the employes including the mananger took their sweet time giving the ice cream cones first and taking the longest time to get me the happy meal that by the time we got the happy meal i could tell they were taking their time to get the food to me i asked them why they gave us the ice cream first if they were gonna take forever on the happy meal???? I have worked at mcdonals before and i know how it works they told me because i ordered so much ice cream is why they took so long to give it to me then i drove off without getting the rest of my food . I went back to talk to a mananger and they messed around and i have a video of how they slow played me that time then try to walk out when they saw me pulling out and try to be smart
