Weird-ass supermarkets

Today after work I decided to investigate what I thought was a supermarket around the corner from the train station in Gif. It was kind of a supermarket, but only for frozen food. It was a strange shop, it looked like they had decided that since all their food is really sterile and processed they were going to go for that same feel with their decor. So it was this weird hospital blue colour with fluorescent lights and stacks of freezers. They sold everything you could imagine, including frozen bread and frozen patessiries. And the weirdest thing was there were actually quite a lot of people in there. I thought the French people actually liked food?
