What gave you that im-press-shin?

no, being hostile would probably have made OP lose their job. subtly correcting them was the key, only if possible.

"So, you want Asian salad?" The Easiest way to correct someone subtly is to repeat what they said, but in the correct way. You're not correcting them, and you get to show them the proper way to say it.

oh i didn't realise i had to point out the sarcasm in my comment, thanks for the thumbs down everyone lol

Not every dictionary has phonetic transcript. Also, dialects can vary by quite a large amount. I mean for example, look at American and British English. That means that there isn't really such a thing as 'correct' pronunciation.

Goo-De B-Eye

People mispronounce words all the time. Simple mistake. It's really not that big of a deal.

7- what exactly is ignorance greater than? Cheese? Elephants? Niether of those, obviously, but you didn't specify.

There's mispronouncing and then there's ignorance. Surely every adult would be able to pronounce "Asian". I would understand if English isn't their first language.

Sounds more like an idiot than a jerk.

#13 beat me to it. Yes repeat their order back to them.
