Customer service, what's that?

A little rant here, I forgot to mention whilst I was in Austria I had the worst customer service experience ever. Ignored, shouted at and insulted, I had to laugh and walk away otherwise I would've burst into tears after I asked a simple question about which train to take. After calmly asking her not to talk to me like a child she growled I was 'too sensitive'. Well, yes I am but that's not the point! I would never have dreamed of saying such things to anyone, let alone a customer I am supposed to be doing my best to help. In fact, they all seemed to go out of their way NOT to help me... Whatever happened to 'the customer is always right'?

What is the worst customer service you've experienced? And let's weigh it out with the best?

I remember when I was working in retail, an elderly woman was so happy with my job she gave me a hug and a kiss... the person next in the queue asked if they should do the same!
