I found taking the traveling overseers out for a meal, to be a waste of time. Our literature regulary spoke of the upbuilding talk the local congregations received by entertaining our brothers. Now some of the modern COs look at their telecommunication devices, talk of things not related to our ministry or phone it in.
If you are a young one who desires to take the T.O. out for a meal, make sure you don't invite non stop talking brothers or sisters to your meal. It sucks paying for a meal for a person you don't even talk to or get a "thank you for your kindness". I had a sister join my group, all she did was talk of her abusive husband (he's not abusive, he's gentle!), while the others talked of getting old in this "wicked system that's on it's last heart-pump!"
Don't invite two TOs to a lunch with you, they will not speak with you and chat with each other about busy-stuff. You spend $100 on lunch to pay two, four, or six rude people, who pretended you did not exist until it was time to pay (they shove the ticket your way) and rush you back to the Hall. I feel bad for new dubs trying to make friends with TOs, it's a waste of time and money. You are better off to spend that money on your wife, husband, kids or Mom or Pappy. What's your favorite lunch-TO story?
