I don't go to jack in the box often. However I've never really had a bad experience with one.
The service here sucks. I've come here twice with this last instance being the last time I bother.
I've walked in both times.
It took about 15 minutes to get a single jumbo jack last time. It wasn't busy.
Today it took 3 minutes with me being the only person in line and two people looking right at me and not taking my order before I left.
Management should consider an overhaul of their employees. 5 guys will continue to get my business over you. They seem to take less time than you do and they're a walk in burger place.
