DBC always started and ended the same way - "Good to see you" at the beginning and "I'll see you next time, looking forward to it," at the end. Since she was a horrible actress it usually came across as cliched and insincere. To the point where I would respond, "no you're not" and we'd be off to the races.

1 and 3 always walked me to the door. No. 2 said take care (seemingly sincerely). CW is all over the place.

I don't need a ritual, but if they're going to do it it needs to not be rote.
