Note to all motorists: when you are driving near a pedestrian walking a dog, and they are carrying a small bag that looks like it has something squishy in it, it is not recommended that you piss off said walker in any way. The walker may retaliate with the aforementioned goody bag.
Today while walking Chester (a friends dog I am watching for the weekend), I had two instances where I was very tempted to fling the stinky poo bag at some cars because their drivers were being very stupid.
