McDonald's Retail Crossing a nightmare at lunch times

Took the kids to McDonalds Retail Crossing this afternoon for a treat. Order number 3191 at 14:26 Two issues: It took 35 minutes to get our order, we were in store. Was so frustrated with the wait did not properly check packets. Rooky Error Got home chicken nuggets were missing. One kid didn't get their treat 🥵 I guess lesson learnt don't go to McDs when they are busy
