I wouldn't unless the waiter was an outsider. To be honest tipping isn't such a big deal here as it is in other countries. For instance we never tip taxi drivers here or in Buenos Aires and they don't seem to expect it either.
I don't tip, but maybe I won't ask for change, Let's say the ride is 140 and I give 150, I said 'we're good like this' or something like this. They are always super nice even if you are tipping an insignificant amount.
I guess not coming from a tipping culture, if someone tipped me little money, I wouldn't appreciate it because it wouldn't make any difference. I guess it is just a different approach...
There are freelancing platforms that have introduced tipping. In Translation, there is no tip. But Americans are so used to it that I suppose some translator is making 15% more thanks to this 'add tip' option on these platforms. I am not on them and I was quite offended to see there was a tipping option because translation, web design, video editing, copywriting and the like used to be professional jobs. Letting people tip on those, it makes them look unskilled jobs.
