Does your Ped charge the sick visit fee even when you go in for follow up?

LO is getting antibiotic injections for his eighth ear infection. It's a 3 day treatment at $30/ visit. Today, his ears may have improved enough not to need the third injection, but I have to pony up the dough to make it out of the waiting room. At the rate we visit the doctor or urgent care we could put another LO in daycare for a month! Is your Ped like that too?
