This is a decent store on South Tryon St adjacent to I-485. They have everything you would expect from a convenience store...gas, drinks, hot foods, coffee, beer and my favorite lottery tickets.
The staff can be really friendly here or not...just depends on the day or their mood but you get that at any convenience store these days.
The main reason I keep coming back here is because they once sold me a $400 lottery ticket. Of course that was a few years ago and I haven't won the big one yet but you never know when you will.
