I flew MAD - AMS on Iberia, and happened to sit opposite a crew member on a jump seat. She spoke no English beyond the ability to read the announcements, so I asked her,if she spoke Dutch, as it was an AMS flight. 'No', she said. So I asked her what her second language was, and she said 'English' .
'Hang on' ... I said, 'you told me you don't speak English.'
"Yes' she said : "Ees true, but the person who do me the test, she speak more bad English than me.....'
