I usually bring with me a bunch of $5 bills for tips at ZB or other places. In other words, I already have planned what I will give. If service was absolutely great, I'd be willing to give two $5 bills. But seldom. Has to be GFE with some emotional connection. Reasonable tips and expectations are to the benefit of everyone. If pressure, expectations and/or crappy attitudes get out of hand, many of us may choose to go elsewhere or even, I hope not, stay home. So reasonableness in tipping and, for that matter, pricing, will keep nearly everyone happy. Those who go overboard in their tipping practices end up spoiling it not only for themselves, but the rest of us as well. I want to be kind and considerate, but I also don't want to feel manipulated. If I feel that way, I'll find another place in San Jose to patronize and the place that permits unreasonable expectations will gradually lose business until it is ready to re-enter to good old capitalist system.
