It lacks the store hours!

Most McDonalds in Phoenix started closing at midnight a few weeks ago.

Some lack hours on the doors.

Google Maps has not been updated.

Uber EATs has not been updated. Orders are still going through, and drivers are going all the way to the store, never to be paid for the delivery, customer never receiving the order--this has continued for over 2 weeks I corrected.

I went to one at FLW and Loop 101 with no hours posted on the door, and the managers yelled at me from inside "You can look up the hours on Google Maps!"

I did, and Google Maps said it was open 24 hours.

And now McDonalds own app does not even give the hours!

That is a zero rating.
