I wonder if it is true, though beta. She is certainly putting an interpretation on it, isn't she? 'because I was an English female and they don't talk to females they don't know' - how does she know that's why, if they didn't talk? 
I think she is talking bollocks TBH. She must have been around Belgrave road area if I'm understanding rightly (not that it matters but that's where I think she's describing).
If someone refused to talk to me on the street while I was lost, I would wonder why, but wouldn't immediately assume they 'don't talk to females they don't know'. Especially not right there!
She was driving, right, so I wonder if she was cruising around shouting out of windows or something (I wouldn't reply to someone doing that).
I know Leicester and the sort of area she's describing well, and I simply don't believe she's not hamming up what happened.
