If I order Nachos BellGrande and I accidentally get Nachos Supreme, I swear someone will PAY DEARLY.

There's a 33-year-old woman named Brittani Felton in Flint, Michigan.  And earlier this month, she went through a Taco Bell drive-thru around 2:00 A.M. . . . and the employees got her order wrong.

And she was VERY upset over not getting what she ordered.  So she took out her purple handgun . . . and fired a shot into the building.

The county prosecutor says, quote, "Apparently she wanted her tacos, or her chalupas, or whatever."

Fortunately, no one was hurt . . . but the cops tracked her down, and she was arrested on two felony counts:  Assault with intent to murder and firearm usage.

She's facing a max sentence of LIFE IN PRISON.
