The restaurant I work at (an the restaurants I worked at before) doesn't allow servers to keep tips. We have to put all of our tips into a jar, and they add all of it up and everyone receives a bit. 80% is shared between the kitchen, host and take-out staff, and the remaining 20 % is shared between 14 waitresses. In the end I get to keep about 2 % of the tips I receive from customers.
