I don't mind tipping, especially if I feel the server did a good job. (Not even exceptional. Just 'good'.) But I am a little concerned about 'tip inflation'.

I don't mind tipping, especially if I feel the server did a good job. (Not even exceptional. Just 'good'.) But I am a little concerned about 'tip inflation'. I am just now comfortable going over 10% (with it's easy math), and it seems 15% and even 18% are fading quickly into the past. I'm not wild about paying 20% or more as a tip, it feels like I'm being gouged.
