Business is slow at Brasserie Lipp. The staff goes about things as if the place is full, each one of them getting ready as a team for something that probably won't happen, each one of them having their own opinion about why business is so slow.
There's nothing to be done about it. Rather, doing nothing about it is the right thing to do, and doing the right thing is to take care of the two customers, the Americans, who've ordered the fish, a bowl of lentils, a green salad, and a half bottle of wine.
All that can be done is being done–making small talk with the Americans, bringing them more bread, a pot of mustard, a small porcelain dish filled with extra dressing for their salad.
