Please do the needful
I appreciate this might make sense in some cases, although I personally fail to see where - it drives me insane, specifically because I used to see it in emails on a daily basis while going through the most ridiculous process to get paid. So, now I associate the phrase with pissing about, vanishing emails, cowboys and offshore IT firms.

offshore IT firms
I think that's exactly the point - it's from someone for whom english is not their first language. I come across it a lot as well, and to be honest I don't worry about it given that it's not their native language.

Worse is Americans who are supposed to speak english and say 'Kindly do such and such'. I won't do anything kindly for someone who asks me like that.

I've had similar requests.
In my case, though, we work for the same firm so it is my ignorance of any other language but English which causes it.
Growing up speaking English makes you lazy.
