Is It Illegal To Go Grocery Shopping (as Requested) For A Senior Citizen If They Hand You Their Card?

I [16F, Florida] have been helping a man at a retirement home (independent living) go grocery shopping. He hands me his card after I write down what he wants on my phone and I go to the store and buy his groceries while he is in his apartment. I only buy what he asks for and hand him his receipt once I am back, I also do his laundry on occasion. However a nurse (who does not work for him but another resident) who helps him around his house said to him that what I am doing is illegal. She says he needs to hire a caregiver to do things like that for him. Now I'm nervous because the last thing I want is legal trouble.
My mom says it's no different than shopping for a neighbor and that if he suspects me of anything he can check his cards purchase history. The nurse has been very insistent to him that it is illegal. Google doesn't help much but I guess this is kind of a specific thing. Should I be worried?
