It's the good old "does she have sugar in her tea?"
I went for my new patient appointment today. I'd forgotten to take the questionnaire with me (Mum took it as it's easier with me on crutches for others to carry, when we went before so I forgot about it) so the receptionist gave me a new one and asked "Can you fill it in? Do you need that gentleman [my dad] there to fill it in?" My straight face reply was "It's my back that's bad, there's nothing wrong with my brain".
The woman was constantly snotty with me, she spent ages looking at the computer to see if I had enough time for an appointment if I filled in the form (which isn't that long anyway), I felt like saying "well if I did you've just spent it finding out!"
Would you complain?
