A customer shooting a gun outside a restaurant to protest slow service is the kind of thing you'd expect to happen in Texas, but no! Other states have gun issues, too: a Florida man was arrested for shooting a pistol "at least" three times in the parking lot of an Orlando Denny's because he was "upset about waiting for his food."
Thankfully, no one was hurt. There are many ways to express one's dissatisfacion: Some people have Yelp, others have Twitter. Some have .22-cal. Ruger pistols.
