Well you're welcome, even though I'm useless!
Lol, how heavy is your accent? I may need subtitles in person.
And that's a brilliant tactic. I just don't make eye contact and move away as far as possible. 
Well, I think you wouldn't be able to tell from my accent unless I spoke for a longer period of time. Then I'd keep jumping, British, Irish, American, maybe occasional Aussie, I don't really know. All I know, I don't quite speak with a single accent in a unified fashion.
So if I'll ever be a spy in an english speaking country, I have to only speak in very short sentences! 
(I do spot a bit of RP every now and then, some words I find better pronounced the American way, I was told I sounded Irish in the past, and sometimes, I think I mix up accents I don't even know the names of... It's... weird. Like me, so I guess it suits me at the end of the day!)
