When you hear someone speaking English, which category do you fall into?

Let’s say you meet somebody,
and the person speaks fluent English.
But it is clear he/she speaks English with a foreign accent.
It seems possible that English is not his/her first language.

In this case, what is your reaction?

1) I don’t care in what kind of accent they speak,
or if English is their mother tongue.
As long as I can understand them, it’s okay. I never mind.

2) I can tell that this guy speaks English not as a
mother tongue the moment I hear them speak.
To be frank, It starts to get on my nerves..
I’d rather speak with one who speaks English my way.

3) Usually I can’t tell just by listening to them speaking English.
Maybe they are from another English speaking country.
