Not many Chili's in Seattle area, although there is one across the state in Spokane where I ate at often when I traveled there for work. Anyway, the big chain around Seattle is Red Robin; a really good burger joint that when national and quickly went downhill from being great to ho-hum. They have the payment kiosks, and since my wife pulls out the CC to pay, I just asked about the suggested tip. Yep, they also suggest 20%. What a racket to catch people unaware.
