I have bought some extra large empty tea bags and use these to dry hop in the keg. I'm sure you could use one of these , I put a small stainless steel weight in with the hops. And you could tie on a piece of fishing line for retrieving .
Sorry meant to say , id tell them to go and get a 6 pack of gold , and enjoy the beer myself . Some people who have been drinking dreadful beer for years will never be able to appreciate a beer that actually has some flavour.
I feel for these poor souls.
