Low tolerance........

I have been in a mood lately where I have low tolerance of putting up with peoples sh@#. Hell have no fury when I am in this mood.
First example - I am next in line to check out as soon as the guy ahead of me is done. Please note he smells like he is wearing as much beer as he drank yesterday. Anyway he is badgering the check out clerk and it wasn't in fun. He was being rude and accusing her of not ringing out his merchandise correctly. He just kept up being a jerk and I could tell he had upset the clerk and really had her rattled. So when she finished with his order and he was walking down the lane to collect his bags to leave I made it a point to say loud enough for him to hear " I am sorry that some people feel it is necessary to be such jerks for no good reason." You see I have low tolerance of jerks.
Second example - While walking through the parking lot approaching the store entrance I see a old frail woman trying to get the door open so she can go inside. I then see two young healthy self absorbed people walk right around the old lady and use another door so they didn't have to wait or help her. WTF is wrong with people. I jogged up to the door so I could help her. She smiled and thanked me and I told her no problem cause the door is really hard to open. Again low tolerance for mean people.
Third example - Obama. He has changed his mind more times than anyone can keep up with. The man is so wishy washy that it is down right scary. I wonder if he even knows what he truly believes in or does he just go with how the wind is blowing. I again have low tolerance for someone that wants to be the president of the United States but has the audacity to believe we aren't going to notice his vague answers and meaningless opinions that he is changing daily. God have mercy on us!
So now you get the idea of what I am talking about when I say I am having issues with low tolerance. I will be going on vacation the week of the 18Th so during that time I promise to take time to get back in the happy place and stop this ranting. I so need to write a fun posting soon.
Got any ideas?
