A social worker providing services for an elderly woman helps by doing her grocery shopping every week. The client is unable to leave her home and purchase provisions on her own, but she receives food assistance through the Department of Health and Human Services. Every Friday the social worker takes the woman’s assistance card and her list of groceries to the local store. A colleague observes the social worker buying items on her own list as well. At the cash register, the professional only provides the elderly woman’s assistance card. What should the colleague do next?
