Suspicious Handicap Driver Encounter. Anyone else encounter this?

Has something like this happen to anyone else? Was walking back to my car on western Hubbard this morning in River north, and this person in his car called out for me waving his handicap parking sign. He asked if I can open his trunk (SUV) and get his hoodie out. He also said he is in a wheelchair. He looked like he was in his 20s-40s For my safety reasons, I respectfully declined saying “sorry man, I just don’t feel safe doing that”. After driving past the same spot 2 min later, he was gone. It could’ve been completely innocent, but don’t want to risk it. Thoughts on whether I did the right thing? Anyone else go through this?
