The day of my initial visit I was told that my follow-up visit will be free of charge (I was paying out of my pocket). Oh-yea, $140 bill slap me in the face, and for my question about mentioned "free follow-up", I only hear from behind the wall "I'm sorry, my bad". In addition, there was a piece of metal stuck in my other eye contact lens, which they clearly see the day of my first visit ("yes, it was there the other day too"), but I was not told about until the day of the follow-up, that it will be very wise to dispose that lens immediately.
