The sun had just barely risen over the horizon when the party reached the market. It was an old rundown super market, and you wouldn't be able to tell it was inhabited from the outside. As the party walks inside they see people set up with their goods everywhere. Some people have tables, while others sit on a blanket or article of clothing with their goods.
After the government had fallen currency went out the window, so now it was all about trading. People were selling all sorts of things, cloths, weapons, food, anything that might be useful for survival. As the party stands there taking it all in a rather large man walks up to them.
"'Ello guys! I'm Mr. G, and this is my market! he says with a charming little smile.
Now, what business might ya 'ave round 'ere?"
