I would assume they start giving them away at 4-6AM. There are too many hoodlums that hang out at the Stony Point, NY 7-11.
I was one of the hoodlums at one in Tempe AZ. One night it blew up from a gas explosion, luckily no hoodlums were there and the employee was only slightly injured. Us hoodlums had no place to hang for a while until it reopened, but now it's an insurance sales office or something like that.
