Drive thru times

I've been to KFC in Benoni just off of Great North Road and the KFC in Northmead for 2 days in a row at around 10pm at night. Both nights the drive thru has been closed as well as being told that they only serve burgers and chicken at that time. I find this quite ridiculous actually as it is late at night and people done particularly like to get out of their cars due to safety reasons.

Please assist.
