What’s the policy on accepting gifts?

So I was filling up the water pallets, when a older guy approached me. He gave me a envelope and at first I said no and he insisted but he eventually left. A door dasher flagged me down for help and he mentioned the guy gave him a envelope too. It contained a encouragement quote and a Aldi gift card. Once home I realized the guy slipped the envelope on my sweater that was on the electric jack. Would I get in trouble?
