The one thing I love about the Hard Rock Cafe is that the staff always seem to enjoy their jobs, and they give better, more friendly service than most 'posh' restaurants I've been to.
That me reminds me of a visit to the Hard Rock in Oslo with my sister and a friend of hers: As you might know, there's free refill of soda, and sometimes they ask you if you want more, sometimes you gotta ask them, which is no big deal..However this one time, as I was about to finish my Pepsi (I always seem to drink up first..), the waitress suddenly appeared with three new glasses of soda without even asking us first.. That's what I would call great service. And before the meal was over, we got even another refill without asking.. I don't need to say that she got a few extra NOK as tips that day..
However, I did also experience once - again with my sister and a friend - that my sisters friend didn't get her hamburger. She asked the waiter, who apologized, and promised her a free ice-cream. When we got the bill, the ice cream was on it.. However, we didn't bother and paid for it anyway..
