This can be down right annoying when it happens to anyone.
Here we have an old fart whose wife gave him a shopping list----or perhaps he had a date that night and wanted to surprise her---Any way this dude with an escort of security and drivers decides to do the shopping himself as he has not shopped for food himself in 30+ years.
As he ambles through the store with security in tow amazed that a loaf of bread is now over a dollar, the nickle candy bar is now 2 for $3.00, along comes someone that wants to take his time to ask questions. Good Grief, this man needs to find this food for one thing, then go glassy eyed at the price.
Ever have that happen to you, you have your list and along comes a neighbor or coworker that get you so distracted and held up that you forget to get everything on the list.? Now, if this is a perfect stranger that keeps yammering in your ear, expecting you to pay full attention to them for what ever reason and after you tell them to excuse you as you have to finish your private business and the stranger begins to holler, yell and point at you--------What would you do??
