Even if shared, low-tip workers will be managed off by the team. On 'decide' part, you simply pay fixed percentage if you are not able to. Even kitchen is motivated that way on a long distance. That works at large scale, not in single case, right. Like a market.
I had some insight into how restaurant teams work. I could write a long post here, but in practice... no, nobody will be managed off, teams will fight internally, discussion about servers/kitchen tips split will both anger and further (if it's possible) divide people, ... Just remembering that stuff makes me sad. Maybe there are some good places. I've seen a few and it's a total mess, inequality, and any
tip pooling leaves everybody upset.
Thinking of it, it's basically a small mirror of the general society with managers as the government.
Unfortunately that's not how it works, unless you also know what percentage of your meal cost goes to them. Maybe the restaurant already pays them a sizable portion of what you spent. Maybe they work for tips only. (regardless how legal that is) Maybe the tips go directly to them. Maybe they're pooled and shared with everyone at that shift. And many, many other questions... You don't know the answers, and nobody will tell you what they are. You're doing a blind bidding game.
If you want to do it and be fair to the servers, you have to tip them the whole amount you think they earned. Do you really want to decide that every time?
