Helpful suggestion

— I can't get a hold of Roger at Larson Brothers Inc. He doesn't return my e-mails, and I've left two voice messages. I need to talk with him soon about renewing our contract.
— I'm sure it's nothing personal. He's probably been busy. Have you tried dropping in in person? It's only a couple of blocks away from our building.
— That's a good idea! I should swing by and invite him to lunch. Everybody likes a free meal.
— Yes, then you can discuss the contract while you eat.
