Personally I find things like that kinda cute. We all have quirks in our language.

Mr Omoikiri, the engineer, frequently makes fun of me because I call the ‘accelerator’ the ‘eggselerator’. I don’t realise I’m doing it. It’s just how I say it.

There are some words that he will never pronounce correctly no matter how many times I correct him. His native pronunciation always gets in the way of ‘news’ (he says new-ss not newz), ‘mayonnaise’ (he say ‘mah-yo-naise’) and ‘vitamin’ (he says ‘vitta-min’). They were borrowed into Japanese with that pronunciation and they’ve just stuck.

Edit: actually I take it back I really hate the way he says ‘news’
