About a year ago I got what turned out to be a really bad bladder infection and went to a walk-in clinic to get SOMETHINGOHGODANYTHING for the issue.
I went with my mother. For one thing, I couldn't really stand that well at this point (hurray for delaying medical advice!), and she drove me (we live in the same city).
When it came time to see the doctor, I brought her in with me (we're close, she hates sitting in waiting rooms, and I hate sitting in the examination room alone, etc. etc.).
The doctor walks in, looks at both of us, and starts talking to my mom.
Doctor (to my mother): So what seems to be the matter?
Mom: Oh, I'm just here with my daughter. She's the one who's sick.
Me: Yeah, I always just bring her in. *begins describing symptoms, I'd had a mild UTI a couple weeks before*
Doctor (tmm): How long has this been going on for?
Mom: Uhm, ask my daughter? I don't know, we don't live together. I'm just the chauffeur!
Me: About two weeks now.
Doctor (tmm): Is she sexually active?
Mom: You should probably ask my daughter...hey, zorbgoink! Are you getting any, haha?
Me: Well, yes, WHEN I CAN PEE WITHOUT CRYING. My partner got checked for a UTI and he's clear, so it's just me.
Doctor: WELL YOU KNOW YOU CAN GET THOSE FROM TOO MUCH SEX. YOUR PARTNER COULD BE GIVING IT TO YOU.
Me: o.O. Uh yeah, I know. That's why he went and got checked. He's fine.
Doctor (tmm): Where is the pain specifically located?
Mom: I don't have the problem. You should ask my daughter.
At this point, I'm too tired to get mad, so my mom and I are both just looking at each other incredulously and laughing a bit. I'm in my 20s and it's been clearly established that my mother and I DON'T LIVE TOGETHER and I haven't told her the intimate details of my pee problem. Plus THE PATIENT IS IN THE ROOM.
The doctor finally decides I have a bladder infection and prescribes antibiotics.
Doctor: so here's the prescription AND YOU KNOW THIS WILL AFFECT YOUR BIRTH CONTROL, YOU NEED TO USE A BACK UP METHOD
Me: Yes, of course. I do anyway, so it's not an issue. Plus, IT HURTS TO PEE, I'm not having relations for a while (smile smile)
Doctor: BECAUSE YOU KNOW IT WILL MAKE YOUR BIRTH CONTROL USELESS AND YOU WILL GET PREGNANT AND HOW WILL YOUR POOR MOTHER FEEL?!
Doctor: So be very very careful! Your mother doesn't want to be a grandmother at her age!
Mom: Uhm, I actually AM. I have three grandchildren and I enjoy them immensely.
Doctor: *STARING AT ME IN ABSOLUTE HORROR* WHAT?! WELL...
Mom: ...I have other children. Thanks for your time.
And we left.
The meds worked, but HOLY HELL BEDSIDE MANNER. GET YOU SOME.
tl;dr - doctor refuses to speak to the actual patient, talks to me like I'm 4, and then makes assumptions about my family.
