Here are some tips on takeout gratuities

Claire asked if we're expected to leave a tip for a takeout order at a restaurant.

Traditionally, tips are for the servers, not the kitchen, because servers' pay is based at least in part on tips and the kitchen staff's isn't. (In some eateries tips are pooled and divided among the entire staff.) But in some instances it's appropriate to tip for takeout food you pick up at the counter, said Rocky food writer John Lehndorff:

* If you have a long-standing relationship with the establishment;

* If the counter person performs a service beyond the usual;

* If it would assuage your guilt at not tipping by leaving a dollar or two in the tip jar. That might be more of a consideration in down economic times, which weigh heavily on the hospitality industry, or if you've ever worked in restaurants.

If you do tip, it can be less than you would leave if you stayed for dinner - say, 5 percent, Lehndorff said.

Denver restaurant consultant John Imbergamo seconds Lehndorff's distinctions, especially when someone provides a service - "which is what tips are all about," he said. Imbergamo tips 10 percent in that case.

Ulises, a reader and waiter, suggests 10 percent to 12 percent, noting that servers and hosts often are involved in preparing to-go orders.
