Customer Service

Why is it that most people in the 'service industry' are so grumpy and unhelpful?  I have had this happen to me over and over again and I still find it very frustrating.  I had one such experience this morning.  I had to call this 1-800 # concerning something about my dental school applications.  I just wanted to make sure that I had done everything correctly and that it was showing up in their system.  I had my conformation # and everything.  So I call, and the first person tells me that it isn't showing up on their system, so I ask her a few more questions and she finds what I am trying to tell her about.  But, she shows something different than what I have.  So she transfers me to another lady.  This lady has a very thick southern accent and was very condescending from the moment she started talking.  I asked her my question and she proceeds to explain (while talking to me like a 3 year old) that the lady I just talked to didn't know what she was talking about because she has that file and no one else knows anything about it.  Ok, then.  So, I finally get my question answered, I did everything right, and my DAT scores will be sent out.  That's all, I just wanted to double check.  Can you blame me?  I mean, this is like a major life thing.  I understand that they probably get sick of people calling with these types of questions, but that's what they're there for.  The money I am spending goes toward their paychecks.  This is why I don't understand why 'customer service' people are always so rude.  The only company with consistently good service I've experienced is JetBlue (shout-out Suzie.)  Don't even get me started on the people I have to talk to whenever I have computer problems.  (Hi this is Tyler, thank you for calling HP, how can I help you today?   Really, Tyler.  You don't sound like a Tyler.  Interesting!  Don, you know what I'm talking about!)
