Worker was probably lying. You claim to be open 24 hours. However went there at 4AM and the person who answered the drive through ( some older guy) told me they were closed. When I mentioned that they are listed as 24 hours he made some excuse that the computers have to reboot at 4. If this is true Corporate needs to inform the public of the times they are not operational, especially if this is a daily scheduled maintenance. Otherwise it gives the appearance of deception. I'm still not sure of the employee was just being lazy and didn't want to assist me.
