Its Paid Service not a Favour

Thank you for the service from the front staff they were great in helping me pick glasses and also when i collected. Eyes still burning and cant really see properly on the rights side with my new glasses but i guess ill have to suffer or my eyes will just have to adjust for the next two years, because when i heard the very same optometrist who was so impatient and rude will have to retest me At Spec Savers Bank city Johannesburg, i was like nah im good, Fyi i pay for the service, dont treat people like you are doing them a favour MR Optometrist. No one likes to complain, but if you dont say anything how will they know?
