Call me kooky

What is with all the noisy call centers?  I just called wamu and it sounded like the guy was standing on the street due to all the noise.  I’ve noticed this more and more lately and I just don’t understand it.  When I was at nintendo i could get a little noisy, but I don’t think it was loud enough to carry over the line.  My CSR experience has been forever tainted by the N.
*update* The whole reason I called is because I couldn’t remember the login stuff for the online banking.  Of course, the username was my gmail account.  ARRRRRGH.
