Here's the difference between Circle K and QuikTrip. When QuikTrip is busy all of the employees will drop everything and run registers until the customers have been served and the line is gone. Then employees who were on breaks or doing something else will return to what they were doing. On the other hand, when Circle K is busy one employee will slowly check people out while the line builds and the other employee will stay outside for her entire 10 or 15 minute smoke break which is clearly more important than customer service. Unfortunately this is the closest convenience store to my work so as much as I try to avoid it, sometimes I can't. Oh, and the parking is terrible. Be prepared to park on the dirt lot and risk dinging up your car because all of the spots are usually full... and considering how long it takes to check it out, it's takes too long to wait for a paved spot.
