That's not what was said. I read the reply to mean that the employees wage is neither the customers problem nor burden.
I've struggled with the concept of tipping ever since I first travelled OS a number of decades ago. When I tip (which I do), it's for service that's been beneficial to me, or was far more than I expected. When I tip, generally I want the tip to go to the person who provided that service. I've asked to speak with chefs as well and tipped them too so it's not always just front of house staff.
My recent Maldives holiday presented a problem. How do you tip at a resort where everything goes on the bill? I had one waiter who hovered so much, it made me feel uncomfortable. I said to my wife he seems to be waiting for a tip all the time, but we didn't carry cash. I'm still unsure if he was just enthusiastic or he hadn't figured out that most guests did not carry cash with them, but that hovering beyond the point of easy banter tends to annoy me. My solution was to add 10% to each bill chit (with the hope that would be shared amongst all staff and not just end up in the Conrads profit statement) and the staff that really went out of their way to please us, without hovering, got US$30 each at the end of the holiday. I have absolutely no idea if that was reasonable, insulting, or just what! All in all, I think tipping is a worthy concept that's been railroaded by the US with their "you will pay, or you will regret it" attitude that fails to link quality service with the overriding expectation.
