A guy getting kids into his garage with candy? Sounds creepy!
He's not a guy, he's a high school boy.
I like the idea of you selling snacks in your front yard as the children come back from school. You won't get punished for absconding from class.
Sounds creepy but it's not as there would be a lot of students at the same time crawling all over the street also OP mentioned about parents picking up their kids , the shop would be the first place to be considered by the police to be involve when related to missing kids or somethimg related to what creepy means to you.
