It freezes a lot. It won't let you cancel a deal and choose another if you change your mind. It won't let you add comments. For instance you may want ketchup with your fries or you may want something on the side instead of on your sandwich. Also in this case where I had an either or order where you get the 2nd item for 29 cent it would not let me choose two burgers. I had to take one burger and one chicken nuggets. I did not want chicken nuggets. It wouldn't let me delete the nuggets.
