Is my ego too big?

I have a chip on my shoulder tonight.  I thought I would be over it by the time I got home, but I'm not.  My family is famous for holding grudges.  I'm trying to fight it, but each time it comes to mind again, I'm seething all over again.

We have this big customer at work.  B.I.G.  He isn't my customer, but I have spoken to him a few times, and his staff a LOT of times.  He is world famous in the industry, and spends a lot of time on lecture tours.  He's in high demand because he's good at what he does.  He really *is* good.  Honest.  Like I said, I don't talk to him often, but when I do, I take very good care of him, just like I do all of our customers.

He was teaching a class at the lab today.  I stayed after to help out with dinner, and to "make nice" with customers.  I like this gig.  It doesn't happen often, and when it does, it's interesting to put a face with the voices that we so often talk to.  I made my rounds for about an hour and a half.  Had a blast.  Cool folks, all of them.  I helped one customer find a computer that had internet access to book a room (since he didn't plan ahead) and everyone LOVED ME!  OK, they at least liked me a lot.

This speaker stopped me as I was leaving.  I thought, "how nice, he actually remembers that we've met twice before, or that we've spoken on the phone!" (I had a name tag on.)  He looked at my name tag and said, "so, you're the one that my staff is upset about...you're leaving customer service, right?"  I said, "No, that's Rebecca.  She's in a new position, and she was great, but she'll do very well at the new job, too.  Trouble shooting and fixing problems." 

Then he said...damn, I'm still mad...he said, "Oh, so you're just Rachel from customer service, huh?"  Then.  He.  Walked.  Away.  No "good bye", "kiss my butt", "you're dismissed", nothing!  Yeah, I'm just Rachel, from customer service.  Nothing more. 

Bull!  I am DAMN good at what I do, and I will NOT stay late to host another one of your classes, butt-head!  I am NOT *just* Rachel.  I do more for my customers than most other reps even CONSIDER!  I am NOT *just* Rachel.  I am very good at what I do, and I will no longer bother myself with trying to impress you, jerk.

Oh, and "Have a good day!"
