I love QT.  I do alot of traveling and I seldom find any city with 1) as many convenience stores as Tulsa, 2) convenience stores as nice as QT.  When in another city I frequently find myself grumbling "where's a Quik Trip when you need one".  They're clean, the prices aren't outrageous, they have a good variety, they're friendly, and THEY DON'T WORRY ABOUT PENNIES!
