Feedback learning and generalization in robotics takes a step forward.

I used to carefully calculate 10 % as a base and then when feeling generous, or for extra service or because she was cute I might run it up to 15%.Now-a-days, I am ok for money so I think about whether a buck or two on the tip makes any real difference to me. I waste or lose more than that often enough so I add it on the tip. I'm almost always over 20% and frequently significantly more.If it's in a small restaurant and the bill is $10 throwing 2 or 3 dollars on the table doesn't hurt me and makes a big difference to someone else.

I'll check with some friends who do that kind of work but I think it is the norm that tips are shared with everone, front and back.IIRC, one thing done is the first 10 % (say) is shared and anything over is the servers (or servers and bus ) or whatever is agreed to or mandated by the place.
