I hear this an increasing amount at work (big professional services co in London) exclusively from younger folk.
eg “Please may you send me the documents you need printing.” or “Please may you check the final point with Dan?” (Might or might not end with a question mark).
This is wrong isn’t it?! I always thought “Please may I…” was a polite way to ask for permission to do something.
But you can’t ask another person for permission that they do something.
It should be “Please can/could/would you….” shouldn’t it? (Better pedants than me will I’m sure be along soon to confirm which of those is correct and when).
I find it really grating!
