On dog ramps

One thing that's bugged me when I was delivering pizzas, was how many people would delay opening the door, making me wait (when possibly I was very busy and had many other orders to deliver) while they reined in their barking dogs. Getting somebody to hold Rover. Or to lock him into another room. Etc. Or sometimes they let the dog rush out to jump on me while trying to get to the pizza or smell my crouch (always fun). All these people knew that they'd ordered pizza and I was on the way, but they never corralled Rover until I actually got to the door. Sometimes I'd see little doggy doors built into a door, so Rover could come and go as he wanted. You could also have dog ramps connecting the door to the ground.
