customers can be so annoying!!!!

[chakkra]

After working as a customer services rep for Boostmobile and Time Warner Cable, I can agree that dealing with customers is one of the worst jobs I can think of.  

BUT in this particular case, I can't see why you were so annoyed by this customer.  The person asked specifically for options A and B, and you gave him option C.  And while it is true that he/she should have listened to your advise, if you're gonna get annoyed by such small things then your days working over there are going to be much worse than they need to be.
