While resupplying their food stores ,they come up with a request? What was it?what does it result in?

Here is a quote from the text,

We had insisted at all the shops we had been to that the things should be sent with us then and there. None of your “Yes, sir, I will send them off at once: the boy will be down there before you are, sir!” and then fooling about on the landing-stage, and going back to the shop twice to have a row about them, for us. We waited while the basket was packed, and took the boy with us. We went to a good many shops, adopting this principle at each one; and the consequence was that, by the time we had finished, we had as fine a collection of boys with baskets following us around as heart could desire; and our final march down the middle of the High Street, to the river, must have been as imposing a spectacle as Marlow had seen for many a long day.
