Hmmm......I'm not sure I agree with that at all.
Speaking as a foreigner/immigrant, the American tipping culture takes some getting used to. Being British and used to buying each pint from the bar for cash, it took me a little while to understand, on my first trip to the US, why the barman was so damned grumpy (even though I understood that tipping is expected in America, and would have left him some money on leaving).
I don't think you can describe an arrangement where a waitress makes literally next to nothing (isn't the federal minimum for a tipped employee $2.13 per hour?), and the customer is expected to tack 20% or 25% onto his bill in order to ensure she is sufficiently paid, as "a little extra for doing a good job." Likewise, when I look at the check and it says, "For your convenience we automatically add an 18% gratuity for parties of 6 or more," that doesn't exactly represent a voluntarily provided extra little reward for a job well done.
Also, for repeat customers, tipping is indeed paying people to be treated well. I wonder how quickly the club member who is incredibly cheap with his tips gets served at the bar, as compared to the member who wanders around from time to handing out $20s and $100s? Even in more modest environments, wait staff naturally provide better service to those who are known to tip better (and who can blame them)?
The question of why someone's actual salary should be framed in terms of another person's largesse is highly problematic. Personally, I'd rather the food was 20% more expensive, the waitress was properly paid, and I didn't have to tip her. Under the current system, refusing to tip someone who has served your dinner just because the food was bad, or because you are, by nature, a cheap p***k, is still, to all intents and purposes, stealing from the person providing the service (if only morally).
To the original poster: I hope you enjoy your round at the upscale club. I'd be too nervous and self-conscious to enjoy it - from worrying about parking my old SUV in the parking lot, through to hitting some horrific slice under the gaze of a professional caddy, through to thinking that the staff were resentful of being stiffed on their tips, because, as a humble college professor, I couldn't tip as well as, say, a corporate attorney. Being out of one's familiar economic environment is often a disquieting experience.
Luckily, golf's a broad church! Looking forward to my Friday morning hack around the muni...
