McDonald's

After one drive thru being closed and waiting 15 minutes in line to get food they left a sandwich out of bag and gave me a small fry in a large box. When I ask for them to up my fries she put them in a separate bag and handed the same ones back. I told her to keep them if they wanted to be so tight. Then told me to pull to a space for a missing Sandwich after waiting 15 minutes in drive thru. I said no forget it. This is poor customer service…
