Food delivery

There was a knock on my door, right on time. I waited a little before opening, so the bags were already sitting on the doorstep, and the smiling grocer waved and stepped into the car. 

This service really keeps me on schedule, and I am grateful that they deliver to the village where I live. The distance is about 9 kilometers, and the charge is 9.90 euros. Does it cover even the expenses, I wonder?
