The exploit relied partially on the negotiations being conducted in Cantonese, so the matron of honor asked for "500 lumps [of money]", with most/all currency using "lump" as the measure word. The same thing could have been done in English, had he figured out which of the world's various currencies called "dollar" had the lowest exchange rate vs. the USD. The exploit was helped by the fact that Cantonese treats currencies more uniformly than English, so it's syntactically easier to substitute a different currency.
(My friend just went to a local bank and asked which currency they had on hand that had the lowest exchange rate vs. the USD. It happened to be VND.)
While I've got you... I've heard "ya man" for HK$ 20 in the North Point produce market in Hong Kong. One of my friends said that this is a "local count", but didn't give specifics. I'm familiar with the normal "yi sap" for 20. When is "ya" used for 20 in Cantonese? (Side note, 20 is "yi sip" in Thai, despite "yi" not being 2 in Thai... an interesting borrow/carry-over from Southern Chinese dialects.) Is "local count" something more formal than slang? I know it's written as two tens in a single character, but I'm guessing Canto slang also has dedicated characters in some cases.
It was definitely Cantonese. My buddy's father-in-law only speaks Cantonese (grew up in Manhattan's Chinatown, poor enough English that he thought his son-in-law Dave's name was "Day" for long enough to spell it that way on his new-year's red envelope) and his daughters are bilingual in Canto and English.
Heck, even had one code challenge pre-interview a few years back at x2-x3 the salary I was aiming for at the time, for a C++ role, even though my total experience of C++ is half of one job that I only stayed in for about 15 months. Obviously I didn't get that interview let alone the job, but that's why they don't just rely on the contents of self-promotion documents we write and which they barely read.
I've had a few messages saying "you won't get many offers with that rate", which is kind of the point! That being said, if anyone seriously did offer me fifteen large for each of the three days minimum (two travelling days, at least one working day) then I'd take it...
Don't say "No.".
Instead think about it, figure out how much it would be worth TO YOU to do the thing, add some, and quote that.
A friend with his own firm/ consulting practice was an expert in a particular kind of database work, was asked by IBM to do a months-long project in Turkey (iirc). He didn't want to go but used this approach. A week later he was in Turkey (they didn't even blink at his outrageous quoted price). Said it was totally worth it because he'd taken that approach.
Bit if you're just looking for validation from the internet to not be polite, then here you have it - it's ok if you don't respond to a recruiter who you don't want to respond to.
Spam does not deserve a polite response, and responding to spam is, in fact, detrimental to the rest of the Internet and rude to the rest of us using it.
So you are being rude when you do respond to spam - and including LinkedIn spam.
The companies that such people are attempting to recruit for, probably share my dislike for those that can't tell the difference between platforms or languages.
