It's the same effect.

If you want pain meds, I'm sure it's easy at any of those "pain management clinics" I see advertised.

If you call a few doctors and ask "Does your practice handle worms? I'm worried I might have worms," you'll have at least some of them say "absolutely, all the time, come right in".

If they want a happy customer and they know your expectations and they know the risk of dewormer is low, then they'll probably go along with it to make you a recurring ~~customer~~ patient.

You might not even know you've accidentally guided the doctor in that direction.
