No that’s not true.
often first interactions involve kinda standing near someone, awkwardly making eye contact, then one person makes a quip about something (usually sarcastic).
For example, imagine you’re waiting to collect your child from school and there’s another parent nearby. It’s raining. You would make a bit of eye contact and smile. Then you could say “this rain’s a bit much isn’t it?” - said with a grimace and a small chuckle. Then the other person would agree and also make a sarcastic quip about the weather. Then you could say “is your child in year 1 too?” And they’d say yes or no. If they want to talk they’ll continue and ask you a question back. If they don’t want to talk they’ll probably kinda put their head down and just stop talking or go on their phone or just generally not try to keep chatting.
if they keep chatting, just before the conversation is about to end you might say “what’s your name by the way?” (The by the way is to soften the question and make it seem casual 🙄 we’re a troubled nation)
Or if you couldn’t ask what’s your name, you would smile at them upon seeing them walk up (not too intentionally - keep it awkward and casual) and say “I didn’t get your name the other day?”
BUT quite honestly the nuances of this country’s awkwardness are pretty extreme. Even people from other English language countries don’t get it. Sarcasm and complaining is a bonding exercise. It’s very hard and I’d be inclined to say be yourself and don’t worry toooo much because you’ll find your true people by being yourself. Life is too short to fake it. I would advise turning down the bluntness though as we are genuinely really sensitive and just can’t cope with that. Being honest I’m actually surprised that the woman you were rejected by was so blunt. Unless she’s just a rude woman, you must’ve really pissed her off. Although maybe she’s got big hormones atm?
Edited to add about the work question, no I wouldn’t just say what do you do? I’d try and talk about anything we might have in common first, anything situational, and then after a few times of speaking you could ask something like:
so, do you work around here?
or
a friend of mine is worrying about maternity leave, I’m a stay at home mum so I didn’t do that - did you take maternity leave?
or
what are you up to for the rest of the day?
And if they say they’re working you say oh where do you work?
it’s just about making questions less probing and direct.
