I have a similar problem whenever I cross between multiple countries in Europe and encounter the first motorway toll in a new country. No matter how hard I try as I approach the toll I always greet/thank the person in the booth with the language of the country I've just left rather than the language of the new country (happened to me again last month driving from Portugal through Spain and in to France). My mind just goes blank. Seconds after pulling away the word/phrase I wanted pops in to my head - it infuriates me!
