How does everyone tip out there and what is your personal etiquette? Do you tip after or before tax? Do you tip 20% on wine and drinks or maybe a little less on those items? My rule of thumb is if the service and experience is great, across the board, I tip 20%. If it is good but could have been better, I tip 15-18%.When I am at a cheap place, I always tip good unless the service is shameful. But when at an expensive restaurant, where you are paying top dollar, can't you be more discriminating? I'd like to hear from those that are not afraid of ex waitors and waitresses, being treated badly on the next visit, etc. I know food service people work hard but shouldn't there be a scale from 1-10 and you are tipped based on the quality of service? Curious on your thoughts, my friend looked at me like I was cheap and horrible last night when I chose to tip 18% on a 271.00 bill for 3 people which included a 50.00 bottle of wine.
