They're either not using the silver conductive ESD paste on the screen, not applying it correctly or they're not using enough.
Without the esd paste, the screen gets a lot of static, which you picked up on.
A quick way to resolve this as a temporary fix, is clean the screen with isopropyl alcohol, you'll notice the static goes away instantly and doesn't come back unless you cause a static charge on it (rubbing it fast with clothing etc)
I know your answer to this.
Tell your refurbisher to refurbish better.
