In the town of Windsor, Massachusetts, an enclave of 984 people settled in the Berkshires, there is a convenience store called Sangar General Store. Get there early enough and you may snag one of their Indian samosas. The fried savory turnovers are a regional legend. People will travel a considerable way in hopes of getting one. The store regularly runs out.

Why aren't more convenience stores like this? Some chains are trying. Not Sangar's samosas — you still have to head to Western Massachusetts for that particular treat — but all sorts of foods for various parts of the day that might bring in customers on the promise of an aroma.

As a Placer.ai report from April noted, food has become one way for the big names to draw consumers in. Casey's has grab-and-go breakfast items, including breakfast pizza. Maverik has burritos and items that would seem to go far beyond the first thing you'd have in the morning, such as "made-to-order street tacos and burritos, cookies baked in-house with whole ingredients, loaded nachos, and steaming bowls of chili mac" created by a legit chef, according to Thrillist.
