We could spend a lot of time debating this.
I would be uncomfortable with breaking for that half-hour because we have only two hours available to us. I think we've had meals in the past. Other committees do the same thing. When we can, we fit it in. If you're asking questions of witnesses, obviously you're not going to go back there, but it does provide room for other members of the committee.
Let's deal with it as it comes along. If it does become disruptive, I'm prepared to reconsider it, but I think the normal practice has been that we just go back there whenever it suits us, fill our plates, and bring them back.
Is that acceptable to everyone?
