This is ridiculous and incredibly unfair to the service workers. You're not sticking it to restaurant owners by refusing to tip, you're just being an asshole.

How? It is optional and plenty of other people are not tipping. I think you're being an idiot for throwing your money away if you tip because you feel forced to. If you tip because you appreciated the service then it's different.

No it's not and no there aren't! I can't believe you think this is normal. Not tipping unless you particularly appreciate the service is like... dumping your fast food trash out the car window when you're done with it. You can probably do it every week for years and get away with it but it's awful behavior.

Yes tipping is optional. If we can't agree on a fact we won't go really far.
