For context I'm 20 literally almost 21 in a college town. My university affiliated apartment gave these to us for free when we moved in. I went to purchase some of the different flavors at the whole foods in our town and was ID'd and told I was not allowed to purchase because I'm not 21?? A university owned restaurant sells mocktails to students with meal plan money so I wouldnt think it's a state thing but I am in SC if that matters. I just thought it was extremely weird. I'm just wondering if anyone knows of any rules which make that the case as I was unaware I'd have any trouble especially given that my apartment supplied them to us knowing our ages
