At the supermarket
What should you do at the supermarket?
The supermarket is a popular place for people from all walks of life to meet. Apparently this is where most people meet their spouses. Why not go out there, make a new friend, meet some interesting people, have fun?
Some supermarkets offer wifi, and a place to sit. What more could a writer ask for? (Peace and quiet. But you can do some social writing at the supermarket.)
