Adopt a Pet Peeve
If somebody asks you to email them something, just forward it and please stop using "as per your request" in your reply. It's a ridiculous, archaic phrase and it's starting to make me want an as-per-in.
If you feel you must add value by typing in your own words, I offer these simple, pleasant alternatives:
"As reqeusted ..."
"Here you go ..."
"Let me know if you need anything else ..."
"Here. Now leave me the fuck alone, I've got work to do."
Thanks.
