Today is a Good Day To Rob Convenience Stores With a Bat'leth

What kind of Klingon robs two 7-Elevens at 2AM with a Bat'leth?

The kind of man who would leave the second store empty-handed after the second clerk refused to give him money. Now that's just shameful. Perhaps if he had threatened the clerks in actual Klingon, he would have had more luck? [Denver Channel - Thanks Undercover Buck!]
