CosmoProf Beauty review: customer service

I've been a salon owner, Esthetician, and in the beauty industry for 17 years. I've been shopping at this location for five years. After spending 30 minutes choosing products for my hairdresser who was unable to pick up her usual supplies, I was told at the checkout that they would not sell to me because I was an Esthetician. Even though I have spent a lot of money at this store over the years for my business and previously bought hair products as well, I had to return the product to the shelves and go to another supplier. The lady was incredibly rude and unprofessional. I've never had this happen to me ever in my career.
