OP spent the evening drinking with her friend, not carousing with a table of strangers who hurled abuse at her friend.
OP has explained she didn’t slag off her friend at all. She just didn’t jump to her defence when someone came back from her table shocked that they’d been told very rudely to fuck off. Because there was no call for it (she felt “mortified”).
These are people who had, earlier in the evening, “mingled with” both OP and her friend at their own table. Towards the end of the evening, OP stopped to chat for a few minutes with them on her way back from the loo, and that’s when the friend was invited over and told them nastily to fuck off.
Knowing her friend was feeling antisocial, OP, given a chance, would have protected her from this social encroachment (“they were gone before I could stop them”).
OP then gets sacked by friend who storms off and later won’t engage with any apologies, responds nastily, and presents a distorted view of what happened. Maybe you choose to believe her version, but OP’s account of a night out in a beer garden post-lockdown sounds perfectly normal to me. Towards the end of an evening drinking with your friend at a separate table, people who’ve been friendly with you both earlier chat briefly again in passing and wonder if you both want to join them for last drinks.
This happens all the time, no? I think by the end of an evening’s drinking, most people’s social boundaries are softening a little (that’s the whole point of alcohol, surely?) and especially now, after lockdown, it’s exciting to meet other people. Sounds as though OP’s friend is terrified of it, and “COVID paranoia” could well be to blame.
It also sounds as though the “friendly crowd” was dead set on making as many new friends as possible that night, and OP was piggy in the middle, having to deal with a surly friend without being rude to people who had been friendly with them earlier. People talk about OP’s friend feeling humiliated, but the OP clearly felt humiliated too and so would I in that situation.
“I was embarrassed at the time she'd told these friendly people to fuck off. They were just being friendly and whilst she didn't have to engage with them she could have said 1000 better things than fuck off.”
I can’t believe I’m brave enough to lock horns with the legendary Bluntness! 😋😉 But that’s my penny’s-worth.
