Not sure what the problem is here. Plenty of staff. But horrible wait times ...lots of personal conversations among staff rather than focusing on getting our food in a timely matter.
Why don't you install a timer on the drive their windows like some McDonald's do to make sure the drive thru is being attended to.
Only reason I come back here is there are not a lot to choose from nearby
Update 5/13/2018 please fix this please it has gotten worse.
