I think this is due to where you are on the path of learning English, and maybe because people feel more comfortable asking to repeat something when you are talking amongst not natives. Also not natives speak slower.

Comes a point where you get so used to what is, admittedly, such a weird and non sensical pronunciation, that the same mistakes I used to make as an Italian native I don't understand at all from a Spanish native that doesn't pronounce as well as I'm used to. Only after I realise what the word is I understand where they are coming from.

Also the every day vocabulary is not that big and fancy, I tend to use some "fancy" words sometimes just because that's the word I would have used in Italian, and it's correct in English, but not widely known. Then again I'm now reading Stephen king and having to use the dictionary every few pages, just because something is mostly obvious by the context but I want to double check.
