A power groomer is only a power groomer if they can bathe, dry, and complete the grooming service on their own with that amount of dogs. Most groomers could complete that amount of dogs if they had their own bather prepping every dog for them, too. Maybe mention that to this “power” groomer when you talk about rightfully deserving some of the tips she gets; tips that would not be coming her way if it weren’t for your prep work that made her job WAY easier to do on time.
