This is one of my favorite fast food places for two reasons. 1) They don't bat an eyelash when I order no bun. They just ring it in and make it properly without a fuss like McDonalds or Burger King (and the product quality is better than a lot of competitors). 2) They have two of the touch-screen choose-your-own-drink machines. Nothing annoys me more than getting stuck behind someone who needs to put 35 flavors in one cup or who can't choose between cherry and lime and holds up the line for 10 minutes. Having two machines let's me use the other one to get my coke zero in a hurry. It's like having a fast-lane.
