If overtipping is your bag, then there's nothing stopping you from tipping regardless even if there's a service charge on the bill. You'd still get your precious karma and endorphins...Ixtellor wrote:1) It does result in better service if you are a repeat customer.

 on both counts.
The only citations I've seen in this thread are the two newspaper articles linked to by the OP. And yet everyone's rushing in to counter them with matter-of-fact claims like these, backed up solely by anecdotes.
I just finished reading/skimming 6 major studies on tipping.
I can not link them because they are password protected and not copyable.
But here is a link to a good abstract and ok abstract on one of them.
http://www.accessmylibrary.com/coms2/su ... 185959_ITM
We find that tipping and reputation can evolve over time in four types of paths, described as follows: (i) tipping and reputation converge to an interior stationary equilibrium with tips above the minimal level and positive reputation; (ii) tipping decreases first and then increases indefinitely, while reputation increases indefinitely from the beginning; (iii) tipping converges to the minimal tip and reputation converges to zero; and (iv) tipping and reputation increase indefinitely from the beginning
The conclusions seem to be consistant.
1) Tipping has a direct correlation to reputation. The more you tip the better your reputation.
2) Tipping is a valuble tool to businessess, in that it saves money in both wages and in oversight. Instead of hiring an extra manager, you can just use the tip's as a way to monitor and ensure good performance.
3) In terms of big tipping = better service, all the studies are inconclusive to causality. Or make exceptions. Best example is in the abstract I linked.
Azar (2005a) incorporates social norms and feelings of fairness and generosity in the customer's utility function. He finds that while in general tipping improves service quality and social welfare, the equilibrium is crucially affected by the sensitivity of tips to service quality. When this sensitivity is high, tipping can serve as a good monitoring mechanism and support an equilibrium with a high service quality. The lower this sensitivity, the lower and farther away from the social optimum is equilibrium service quality.
I don't think I answered all your criticisms.
But there are numerous studies out there. I will try to find a way to link the 'big' definitive studies on here that isn't pword protected.
I do think it is safe to say that big tipping is ultimatly beneficial.
