I really dislike people!

Okay so not only did I drive 2 hours to get to the inventory last night, I got lost, then I got yelled at the second I walked in the door. Not to say that maybe I did not deserve it, but come on. I meet our new Sales Manager and she was the lady I was hoping I remembered... so I was slightly excited and yes I got yelled at to be quiet... kinda made me feel like I was in the 3rd grade or something... also made me feel like turning around and walking out the door! But that was not the worst of it. You know me, gotta stick up for my peeps... so about an hour later we got called to a meeting, and the lady in charge asks where's the scruffy guy, and I totally did not pay attention... not one of my employees... then where's the scruffy guy from Hagerstown... still did not quite sink in... I drove with a guy from our inventory team, and a lady drove down herself from our inventory team and neither were scruffy... but alas this horrible lady was referring to the guy I drove down there with. Now we kinda made it into a joke... but the more I thought about it the more I got pissed, and yes as a supervisor now I realise that I have to watch out for my peeps. I think we should have just left at that point... but no we stayed, because we are good employees... then to add insult to injury I went outside to get some fresh air and the same horrible lady told me, while pointing at "scruffy" guy take the big guy with you... are they just rude like that in VA. We still stayed, that is until I had an asthma attack... then WE LEFT!!!!
It just reaffirms my dislike of the majority of people because no one in our society seems to even think twice about being nice, civil, or friendly... sad times we live in!
