Unhappiness

I was at the grocery this morning, a Sunday morning ritual I could do without but a necessary bane to my existence if we are to eat. I was window shopping along the freezer case looking for new and exciting options (I found none) and an employee was behind me stocking another case. When an old woman, I say old in hindsight because of her behavior, turned the corner and loudly stated, "Well I can't even get through here! " Not "excuse me" or "pardon me" and when I say loud, I mean everyone on the isle turned. I pushed my cart forward to allow her to pass between me and the employee...who was unloading a big, heavy looking, flatbed full of boxes. She just stood there. I knew she had enough room to pass, I returned to staring at frozen quick meals. She then declares to the employee, "I guess I'm going to have to wait until you are done." Again, everyone turns to see who is disturbing their tranquil Sunday morning shopping. She begins to inquire how long he is going to be, how much he has to unload...he answered much more polite than I would have. Turned out she wanted something from the display next to where he was working. If she had walked to the front of her cart she could have simply reached the object of her desire, but instead, she berates him until he moves so that she could push her cart into the now vacant space and retrieve whatever it was she wanted. I could hope for tranquilizers or mood enhancers but I doubt those would be in the frozen food isle...though ice cream comes close. I wondered it she had always been such a bitch or was this some part of the aging process? I mean you never hear the term, young and crotchety. What made her so unhappy? What made her so entitled that someone should stop working and move to avoid inconveniencing her...why so inflexible? If I had wanted something dead where he was standing, I would have asked politely to be handed what I wanted. I just don't get it...there is enough shit in the world to deal with without your crotchety old ass being rude, way too early on a Sunday morning.
