Transporter Left The Truck Toolbox

My driver just informed me that one of the transporter have left his truck toolbox in our store today. Busy body driver was telling me how complete tools the transporter keeps in the toolbox. I think that is for sure, how could a long distance truck on its way without the toolbox? Truck is their only 'tools' to earn money, of cause they have to take good care of it. Don’t they?
