when a person asks:
"What's a good place to get antibiotic cream in
foreign city?" and someone responds, "You shouldn't use antibiotic cream."
Or, "Who has a good recipe for tuna noodle casserole?" and someone responds, "You really don't want to eat too much tuna. It's best to eat lower down the food chain. Better yet, go vegan!"
