First, I tried the Night Owl that's down the block, then kitty-corner. It's my preference: the middle size is on sale, and the flavor and consistency is slightly better than at 7-11s.
But, the "cola" cylinder was in defrost (!!!). Gah. That almost never happens at that store.
So, I crossed back to my block, and tried the 7-11 on the corner. But there was something was wrong with that cylinder: it wouldn’t extrude the slushie.
So, I went to the 7-11 that was past my building, across the street, and down the block. As it turned out, that one worked. But if it hadn't, I could've gone around the corner for another block and caught the Hungry Jack's (Burger King) that's having a $1 sale on slushies. And if the line was too long, I would've doubled back and visited thethe 7-11 under the shopping center, near where I catch my bus.
So, five different cola slushie options within a three-and-a-half block strip. It’s good to have multiple layers of backups. :)
Put differently: my work location is optimized for slushies.
