They grocery shop for themselves in my town. Problem is, it's their favorite social activity, and they have parties in the aisles side by side.
The trick is going on a weekday morning, though often that's when the stocking is getting done so there's pallets all over the floor, blocking only the things I want. That, and the fresh meats and produce are hit or miss as they're sometimes not out yet.
Wish we had a butcher shop in town, though they do at least have a butcher like counter. Also carry beef hearts and occasionally kidneys on the shelf. Oh, and eggs are still only $6.50 for 18 somehow. Definitely not the worst grocery store I've had to rely on.
