I know everyone has them.
Some of mine are:

I hate when people just stand in the middle of an aisle in a store talking taking up the whole aisle and ignore everyone else.

Or

How stores(at least where I live) redo the store and make the aisles smaller making it almost single file to make it down it with a buggy

Or

How a person will go through every page of the movies (and read the description of each one of them)available at the redbox only to rent something from the first page or walk away with out getting anything.


So what are yours?
