People tend to check in during these times:
Great service. Good beef burritos.
Don't stop in the middle and block the thru traffic at the drive in, like some folks
Half priced drinks from 2 to 5. It's cheaper to order items on a combo individually than as a combo during those hours.
They charge for extra cheese and red sauce.
They need signs and parking lot markings for their drive thru lane...people enter it from any point and are only too happy to cut in line.
Bean burritos with extra cheese - my favorite for over 30 years!
