You have got to be FIRM with these fuckers holding the
needles
If they cannot get it at first try , they will never get it. DO NOT
let them try try again, you are not target practice.
Tell them - "Sorry, please get your senior nurse or supervisor here
to draw my blood, I don't want you to do it"
They will LL have to get someone else. Don't get stuck with those
nuses who DIE DIE must prove that they can do it.
These things either they KNOW or they DUNNO.
Heck if the fucker KPKB & take long time to locate vein, you
already can tell he/she won't be able to do it - can request for
someone more pro already
