Special delivery

A couple of times over the summer I left the house to walk the dog and found a piece of half-eaten food on our front (outside) windowsill. I think one was a soft pretzel; I can't remember what the others were. Today I got home from work and found a hot dog with mustard and relish and one bite missing. I'm not sure what to think. I'm all for home hot dog delivery, but the execution leaves a little to be desired.
