I just got back from buying some groceries . The man in front of me had gray hair . His fingers were all bent and it took a long time for him to write his check . He looked to be about 80 years old .

Question: What may be a valid thing the gray - haired man was doing ?
Answer: He may be getting his social security check .He may be getting a haircut at the saloon .None of the above choices .He may be interacting with a cashier .
