I hate this kind of thing too. Other people joining in when you're trying to talk to someone privately... 
Sounds to me like this woman's husband is a bit controlling to me. Listening to, and butting into his wife's conversations, giving her no privacy, and intruding on her calls like this is highly alarming.
Also, what pisses me off, is this one friend I have (who is generally OK,) always, always, ALWAYS gets a phone call when we're having a coffee in costa or starbucks. EVERY bloody time!
It's her daughter, her mother, her husband, her supervisor, her neighbour, her nan, her son. I see her once every 6 weeks or so for a coffee (that's all, just 8 times a year for 2 hours,) and they see her every damn day, yet one of them always rings her when we are having a coffee.
And she bloody answers.
She is a decent mate, and we go back 25 years, but it's actually putting me off meeting her. It kind of smacks of 'look how popular I am...' Mine never rings because the damn thing is switched off - or on silent - when I am meeting someone.
@AlternativePerspective that is disgraceful. NOBODY should be allowed to 'facetime' on a bloody hospital ward FGS.
One of my supreme pet hates, is when I arrange to meet someone for a coffee or a meal or to go to the cinema or whatever, and they bring someone else. Because 'the more the merrier...'
No, the more the NOT fucking merrier. I don't want some randomer who I don't know, (or care to spend time with,) tagging along... You know them, and I don't. And I was not told about them coming. So fuck off.
