I don't have any feelings for or against Circle K. I'm glad to stop at one if I need gas or an Interstate "comfort" break, but I don't seek them out. I'd always imagined they were pretty stable businesses though -- people are always going to need gas, restrooms and snacks, so I was a bit surprised to see that this one, on Broad River Road next to Rush's and across the street from the defunct AMF Bowling Center had gone under.
On the other hand, Broad River Road near I-20 isn't doing great in general what with the bowling center gone, Intersection Center (virtually) gone, Dutch Square a shadow of its former self, Pizza Hut gone, Hooters gone etc.

UPDATE 24 August 2012 -- El Cheapo is open (and has been for a while):
