What the Hell Is Wrong With You!?!?!?

I work in Customer Service and there are so many times that I want to ask people what they are thinking. It's like they think that all day I have been nothing but wait for them to show up. Okay, I know that's not really true. Because in the grand scheme of things we are all customers and we all work in customer service. I think though that with my job a lot of people see it as menial. Although it's not. And I say that because I am also in the military meaning that I don't just work at a hotel. But it's almost worse (than being in a civilian hotel, I worked in one before I joined). Higher ranks will say really mean things and there's not a whole lot you can say back... Some E-8 yesterday told me that I wasn't listening to him (it was very mean the way it came out) and then something about me being very hard of hearing. I was very taken aback. As soon as I looked at him he was like, 'Ohhh, No, I was playing with you, really.' It didn't matter though. Now not only was I annoyed but my feelings were hurt. He doesn't even know me, how can he joke with me by insulting me??? It took everything I had. I think that is a big issue in the military. We are taught so much not to talk back that when it's appropiate to do so you second guess it. Or at least I do! Oh, now I'm just rambling... I guess my point is... I don't really know... Isn't that annoying???? Also I get VERY annoyed with myself...
