"Eye Unit First time visit ever very unhappy"

I had turned up early as the bus service to the infirmary is once an hour now my appointment was for 4.15 pm but I got there for around 3.40 the reception staff were very polite and thorough asking me my address phone numbers e.t.c. in a crowded waiting room so anyone who was interested could have my info but that's what they have to do for security so no real problem there !! the problems came after; I had taken a book thankfully knowing that they never see you on time even though if you turn up late they can send you away, so I sat & read my book until there was only 1 other person to be seen (after 5 pm) then she went in to see someone so I figured I was up soon, One of the specialist understudies said as I was a new patient I would have to see the boss to which I replied I don't mind waiting as I have a book, then about 5 or 10 min's later the boss came out of their door & the member of staff at the reception said that I was the last patient to see they replied in a sort of mumble and walked out of the department !! I was quite shocked & the receptionist didn't seem to know what to do until another of the understudies came out at which point the receptionist took them back in their room to talk privately then they went & talked with another understudy who finally picked up my paper folder and asked me to go in their office / room where I got to explain my problem, they examined my eye's twice then noticed the consultant behind me & called them in asking if they could just look at me for a moment as they were non-plussed at my problem (I occasionally see certain flesh / skin as green instead of the true colour after talking about my medication they both came up with the idea it could be a side effect from my medication as one of my med's supposedly can give blurred vision but I asked why mine went green they said they would like to see me again in 3 months & left again I am totally disgusted with the manner in which I was treated I waited patiently always polite just reading my book only to have the consultant walk off !! If I wasn't scared about my eye's I would have walked out when the consultant did
