3 Stars only because the deal you get for SC gas. This Exxon is right off of the Carowinds exit.... could not be any easier to get to if you are coming from the I-77 south direction since you turn right in. This station gets a lot of traffic from people coming and going, so it is not unusual to have to wait for a pump. I always get weary of people whipping around the station, but there's only one bank of pumps so it makes it a little easier - a lot of times the two bank system creates really weird waiting lines and then awkward races for free spots when people pull out.
This Exxon has a small convenient store with your typical items and beverages. The staff are friendly enough. I'm sure it's interesting working here since there are so many people coming and going so the time may (or may not) fly by.
Exiting the station can be tricky, but doable. There is a side entrance to the station that can dump you behind it to the hotel and the Frugal McDougals (one way street) and you can come out of the Carowinds Entrance if you really don't want to wait on folks turning out of here.
