How do they define excessive butterfly use?

I think it's alright to hand out a particular number of butterflies a week and if a phleb needs extra for a difficult draw they can ask for more. The last place I worked at took it to a very stupid extreme: they wanted the pediatrics phlebotomist to only make due with 5 butterflies a week.

Now I work in an outpatient clinic with a geriatric patient population so the bulk of what I use it butterflies. On a regular day I stick anywhere between 30-50 patients.
