Recommend
You want some flowers to put on the canopy above your helicopter to keep the birds away, so you ask people what they would recommend.
You've bought flowers before, but you really don't know which ones would work best to stop birds from landing on the canopy and pooping on your helicopter.

You ask for a recommendation from the centaur (せん) that owns the local flower shop. Now he's walking around your helicopter canopy and staring at the birds, nodding.
I hope the centaur recommends a cheap flower... but with your luck flowers that keep birds away will cost a fortune.
