Place it at the end of a short debate or list, after the other options have been raised. Follow a confused reaction with this as the closer, or lead in with no no wait wait before it settles the argument, then cut straight to the next scene without another reaction layered on top.
About this sound
A very short voice clip of a man casually saying he'll put it in the back, delivered in a flat, matter-of-fact tone over about one and a half seconds. It feels funny and dismissively laid-back, like a low-effort decision made on the spot that ends any further discussion about where something should go.
