"waiting time"

Hi..i had appointment on the 10th of april at 11.15am.i was at the reception at 11.10..the nurse five minute later escort me to another waiting hall..i was on my own to 11.35 then another patent arrived with the same nurse..11.45 that patent escorted i don't know where.11.50 the nurse asked me to sit and wait in the room in which the doctor will be examine me..12.5 i left the room because in my condition i get agitated and i have chronic that will make me uncomfortable.??now the question when there is nobody other than me waiting and no one said anything to how long i should be waiting for the doctor who should understand your procedures in waiting time why the hell patent should wait that long..also i don't know when they would arrive to see me in this case..this is not a joke unless they know better in respecting patent time and the waiting for that appointment.. yours Mr. S.MEKARI
