Q: Hey Bill, the person in out to lunch is just starting to get comfortable but now he's going out to lunch. Do you like getting comfortable, or do you think that's a moment to go out to lunch?
A: the suggestion of lunchtime in that video comes up not during the comfortable part, but just after another mistake is made (the second mistake so far). lunchtime is used here as somewhat of an escape from the awkwardness of the second mistake. i may occasionally use lunchtime in this way, but it's preferable to achieve some success just before lunch
