I hate when people at my clinic are not on the same page. I made an appt for my sons vision and asked if he was due for anything, they said no. once we get here I'm told he needs 4 shots. of course he doesn't want them. I usually prepare him the night before and bargain with him lol I took my glucose test before his appt. so the hour can pass. he always sees me get my blood drawn. I hope he says yes bc I don't want to come back -___-
