So true. I had a friend who is from Kansas who worked for an organization that assisted corporations than spanned cultural boundaries to work together effectively. He had a friend who is Japanese. They had a deal. When they both went to a meeting, my friend listened to what was said and his co-worker listened to what was unsaid.
This is absolutely interesting and that's because it speaks of many things. Most of the time during business lunch the topic of conversation is different from the topic of business meeting. This helps in calming down the level of tension, if any between the board memebers, who were involved in the business meeting prior. It also creates a friendly atmosphere.
This is then followed by the fact that many times during business lunch no conversation takes place because the mind now needs to maintain it's focus upon later half of the day, which is equally important.
All energy is preserved during the break time. All areas of concern that need to be addressed once lunch break is over are recollected, so that they will be presented in a better way as soon as lunch is over. At the back of mind everything gets stored. Thus even without speaking a dialogue expressions convey everything.
I get the impression that events of the morning are still being contemplated. Perhaps participants are ruminating over questions for the afternoon discussions. The lunch break provides a welcome break and allows earlier debates/offers/deals from around the table sink in.
