If you’re a fan of lines, and free things, you should be aware that those people lining up outside the city’s four Super Duper locations are doing so today to get a free mini-burger (just their regular single-patty burger). It’s Super Duper Day, you see, per Mayor Ed Lee in 2011, and the giveaway is limited to 100 burgers per location, beginning at 3 p.m. You’ve been warned. [Eater, SFist]
