I got approached by some young guys at the grocery store asking for donations for getting into college. Has this ever happened to you?

I was looking at the peeps selection because i love those things and I got approached by 2 young guys with a clipboard they were showing me they were interested in these schools and wanted to know if i would like to donate to help them get in or something along those lines. I told them I'm sorry but no but the one kept pushing and I said no I don't have a lot of money and walked away. I saw them go off to someone else. I don't know if you are genuine or just trying to scam. Part of me really wants to believe they were genuine but there's other ways to fund raise than approach strangers at a store.
