Don't joke about C4 at the gate! :-)
DFW employee store at C2 and open to the public! Also, nice Samsung Charging Lounge btwn C6&7.
Winter wonderland is being set up next to this terminal. It's going to be very cute.
Good spot to take a nap between flight if you are on stand by and not sure if your terminal will be A or C. It's in between.
There are vending machines and a FedEx drop box right across from the gate waiting area.
Sockets r working now--at least mine is.
If you need to mail something, the USPS drop box is not too far away at Gate C12 around near the skylink stairs.
The sockets still don't work like Jason said
Don't use the bench sockets...them suckas don't work. Try the tower.
