I was once marked down by a lecturer in Austria for speaking with a Yorkshire accent instead of RP in an EFL class. English is not my native language. Now I have a Welsh accent from when I did my PhD in dialectology at Swansea University. I’m proud of it.
I remember being so happy I’d made a friend on my first day at uni. Later that day I heard her mocking the way I said ‘cake’ (in my Yorkshire accent) to another student.
