Famously corrected when walking into a confectionery shop in the UK several years ago and asking for "Two Twixes", the "Twix" being a famous chocolate bar.
Only to be told by the shopkeeper that the Plural should not be "Twixes" but "Twii". (As in radii as opposed to radiuses).
I later learnt that the use of the word "Twii" was made famous by a satirical writer and tv personality in the UK (Vic Reeves). However, it did stop and make me think how strange the English language can be.................
Not sure what any of this has to do with Middle East aviation, but who am I to question it?
