In a radio show (such as APM Marketplace), when a host interviews a guest, the conversation ends with the host saying "Thank you" and the guest saying something similar in response.
Usually it is "Thank you" or "Great to be with you" or "My pleasure".
Often they respond with "You bet", which really puzzles me. I am aware of the idiom, but even that doesn't make sense in this situation.
My questions are:
- What exactly is that supposed to mean here?
- How did it become one of the standard responses to "Thank you" in this context?
- Is it a good response to "Thank you" in real life, i.e. outside of the radio show?
