A 7-Eleven hot dog roller hack turned my $3 lunch into a $9 feast

I was filling up at a 7-Eleven off I-35 near Waco last month and grabbed one of those sad hot dogs that had been rolling since who knows when. The cashier, a guy named Manny, saw me looking at the cold bun situation and said, 'Hang on, try this.' He took my dog, put it on the roller for another four minutes until the skin got all blistered and crispy, then slid it into a bun and hit it with the nacho cheese pump. That thing tasted like a legit ballpark dog for about three bucks total. Next time I went back I asked for the same treatment on a sausage and added a bag of chips and a drink, and it came out to $8.47, which is a full meal deal. Manny told me the trick works best between 2 and 4 PM when the rollers aren't busy. Now I stop there every time I drive that route. Has anyone else found a gas station food hack that actually makes the food better instead of just cheaper?
