Stanton Optical

After finishing my eye exam. I ask the lady if she could do my P.D. and she said very rude voice NO because you are no shopping glasses today. At least she should said No is more gently tone, and part of the exam is giving you the P. D if the customer ask for.
I walked out of the store but I have to come back to ask for something and I heard the same lady was talking about my with another employee. Unprofessional very much never talk about a customer in front if them.
