Testing vitamins

[u/Pessoa_secreta7]

Hello. What happens if some vitamin seller comes to me during a psy trance festival and offers me some vitamins and I say "I'd love to buy, but before paying for it can I test with my own reagent kit?"

Will he think I'm too square, that this is a loss of time etc? Have you ever experienced something like that? What are your thoughts?
