Forgive me if this has been covered in previous topics (I searched but never found anything on this topic specifically). When you call in a to go order, do you add a tip? I typically go around 10% of the order, especially if the person takes time out to go through and verify everything in front of me. Specifically our Olive Garden in town is awesome at doing this, and PF Changs was great as well. Hopefully some first hand experiences can be given on the topic!
