Worst App Ever! This app has messed up literally every single time I've used it! I just tried to use it again but every time I put the coupon code in it gives me some random message about the tip being too much for them to accept. It won't let me use my gift card at all and it won't even let me remove the sandwich from the order so I can try it again. Seriously just ruined my kids' dinner (again), definitely lost money bc I'm ordering from somewhere else now, and probably lost a customer!
