McDonald's Observatory poor quality food and drink

Last night at about 21h20 we went to McDonalds Observatory drive-through to buy a meal. Please see the attached cash receipt. When we arrived at the drive-through, we were the only car there, and we were the only car there when we left with our order. The quality of the meals that we received can only be described as way below the McDonalds standards that we are used to. I have never bought a McDonalds meal and found the quality lacking. Last night our Coke Zero cooldrinks were warm and tasted like tepid water, which was an awful experience in itself. the chips were old and tasted old and refried. Old taste of the chips was disgusting. To top it all off, the burgers tasted like it was made days ago and reheated for us to buy.

Please explain to me how something like this can happen at McDonalds. Is it because of the Lockdown or is it because business is just slow. Please let me know
