According to 7-Eleven's website, the convenience stores were initially named Tote'm, due to the fact that customers could "tote" their groceries away. (Some stores were even decorated with totem poles, a far cry from the endlessly rotating hot dogs that now define the chain's convenience stores.) The name was changed in 1946 to reflect the new, extended hours the stores were open: 7 a.m. to 11 p.m.
(Qwik-E-Mart is the fictional Springfield convenience store manned by Apu Nahasapeemapetilon on "The Simpsons." But it's worth noting that several 7-Eleven locations were briefly rebranded as Qwik-E-Marts to promote The Simpsons Movie in 2007. If you chose this option because your local 7-Eleven once called itself Qwik-E-Mart, you can give yourself partial credit.)
