The correct response is:
**No, because the sample is not chosen randomly.**
The store manager's method of surveying only those shoppers who enter the meat aisle does not provide a random sample of all shoppers in the store. It may lead to biased results, as the people shopping in the meat aisle may have different coupon usage habits compared to those shopping in other areas of the store.
