This double jack is from JITB.. jack in the box.  Hubby and I went to the one on ward and kapiolani.   We had a problem at the drive thru window because the cashier rang us up for 2 double jacks but gave us both regular jacks.  So when we opened it to eat it, it only had one patty.  It took them a long time to give us the right burgers.  So by the time we got the double jacks, the first bites were real good.  Dumb cashier.  We were starving. 😛
