In Texas, esp in Houston and Dallas, majority of the gas stations carry a gun under the counter. The last place I worked had one too. It is kept to use for self defense when your life is threatened in cases like robbery. Pukar, on a student visa didn't own a gun by himself but used store's. And, kaale people always come up with 'You wanna buy a gun, I got hollow point, ... sth mm, etc'? So, gun is easily accessible here.
