I've pointed out sets to people who were voicing what they were looking for but couldn't see it, I've pointed out to people what they were looking for when the staff person they have asked takes a cursory look and then says "No, we don't have that" and I've also pointed out clearance sets that were not stickered to families. Never had anyone less than grateful however I do know that there will be a time when it won't be well received :)
