Forget the big survey idea only, your brother will just get fake smiles. Just stand near the stall for one day and *listen*. Note who orders what, who complains about prices, who shares. My own data on chicken vs veg demand came from a tired office-goer telling me, "Bhaiya, your gravy is gold but my salary is copper." That’s your real answer.
