Does Quik-Stop count? Excellent selection of goods, fresh cooked food, good coffee
For me, it’s bait shops. Something about the familiar smell. Go in and grab a sandwich from the deli, a cold drink and a moon pie. The go out front and side in the shade and indulge.
I go in there every morning after work. They’re giving out free samples at just that time don’t you know 
. Not only do they have everything under the sun, including beer & liquor, their prices are well below those of the ordinary Stop-n-Rob gas stations. They have a huge variety of coffee and make pizzas inhouse.
They are extraordinarily popular. You would not believe how packed with people they always are, but especially in the morning.
This. Here in Wisconsin, the phrase “Hon, I’m goin’ to the Kwik Trip, kin I getcha anyting?” has replaced “I love you” in many relationships.
I’ve always loved convenience stores, because they were part of my independence. We were ‘free range kids’, and every summer morning we’d take off on our bikes (homemade Sting-Rays).
And if we biked to a “Stop ‘N’ Rob”, then we didn’t even have to go home for lunch. These days (half a century later) I’m still spending days out on my bike, and my favorite stop is one of a dozen local Kwik Trips. Especially when they have their old-fashion donuts for 39¢!
And, as it happens, my free-range kid and his fellow skateboarders hit convenience stores for lunch, and those Arizona Iced Teas… 22 ounces for a buck!
When they were skating in Tokyo, I asked about the best food they’d found. The answer was immediate: “Sushi and bento lunches at 7-11s!”
Oddly there is a place nearby that does the same. It is also a bait shop.
But to answer the OP- there are no such stores I would want to hang around in. Maybe Jay and Silent Bob would. 
Exactly.
“Hang around”?
Exactly none. Universally they are gathering grounds, I find, for derelicts who very probably diminish any amount of satisfaction the employees may gain from their jobs.
However, I do enjoy the services of several local 7-11s many days a week.
We’ve had issues with milk from DashMart, DoorDash’s brick & mortar convenience store. We had delivery from them a couple of times and stopped when each gallon tasted “off” even though they supposedly had not expired.
In high school there was a store called Errter’s Market right next to the student parking lot. It was technically off-campus so we would go hang out there at lunch to smoke cigarettes. Oh, and they’d sell us cigarettes even though we were clearly underage.

There are several around Dallas currently. Have fun!
When I was young and foolish and needed money, I spent a couple of months working a second job, part-time, 3 nights a week at a 7-11 (or maybe it was the other brand of convenience store they had in Portland at the time, the name of which escapes me). Ugh. A more pestilent hive of pointless loitering and petty theft and boredom I have not experienced. Such places are now only a last resort for me if I need to buy something quickly. I’d rather get lost in a Target or something.
That sucks. 
Here, we have a local chain of convenience stores called Dari-Mart. Obviously started by a dairy. I always stop there to get milk from them, because it’s so fresh and local. The expiry date is always about 2 weeks out, and the milk lasts 2 weeks past that.
I don’t hang around convenience stores otherwise. Although I may linger a moment or two to gaze longingly at the bags of Cheetos.
I think it’s hilarious that there are places named Pump n Munch and Kum & Go.
I prefer to do my pumping after I do my munching, however.
There is a convenience store on the North Carolina coast called Biscuits n’ Porn.
Hey, that’s walking distance from Kitty Hawk Kites! You can fill up on carbs ‘n’ titillation, then go hang glide on the same sand dunes that Orville and Wilbur did.

The only time I ever “hung around” at a convenience store was when I was 17 and had dropped acid at a Who concert. I was too afraid to go home and potentially get caught, so I stood in a 7-Eleven all night playing Ms. Pac Man. That was all the convenience store hanging out I ever needed to do.
