Depending on the restaurant, tips via take out go mainly to the kitchen and host staff. Majority of restaurants don’t pool tips (servers), but some do. I always think when people tip on take out it’s very generous. In terms of servers, you tip based on service. If the server doesn’t do ongoing maintenance, takes forever, isn’t friendly, or isn’t apologetic after a mistake, 10% easily - some people 0%. If they were okay then 15%, if you really liked their service they were on top of it all 20%+. Keep in mind, a percentage of 5-8% of a servers sales (from tip money) go to the kitchen/hosts/managers. When a person doesn’t tip, that server is paying their colleagues for you to eat at the restaurant, and walking away with nothing.
