Every visit to the store is like an episode of Seinfeld. From the crazy cashier that loves to screw with me to the receipt checker on the way out that thinks he's a Secret Service member, Walmart is full of the most interesting characters walking the planet.
Personally, I've never liked Twitter, and don't see the point of "tweeting" out thoughts in 280 characters or less. It's a lazy form of communication and provides a person with the ability to hide behind words.
You never know when hitting the record button on your phone will translate into something that makes a stranger's day. In the case of an Idaho resident who was visited by a herd of darling deer, it made a whole bunch of people's days.
