I go to a small grocery store. It's known as a produce market in the US, but known as a greengrocers in the UK, where I grew up.
Oh, I don't think I've ever heard of it!  
Oh, they're quite common. They sell mainly fruit and vegetables, but a few other things too.
That's really cool.  When did they start?  A long time ago?
They've been around for a very long time. I prefer them to supermarkets, even though the large grocery stores have such things as gas stations and are in the middle of a large complex.
I'm wondering, are they similar to farmer's markets?  It reminds me of the farmer's market near me.
In a sense. They do primarily sell food, but they're in a building, not outdoors.
