Sticky tile floor, drippy slushy machine, Some arcade games from the 80s across from the clerk and enough artery clogging snacks to stock your car/ambulance/fire truck for the nuclear winter.
Notes
1) You can godmod the clerk in here, starting conversations with him/her
2) There are Civilians in and around the area, and of course, converse with them
3) the basic menu is stuff that you would find in a 7-11 or deli. (think slushy machine,chips,candy, pre-wrapped snack cakes, snacks named after sound effects and the like)
