This act of scabbyness can range from being accepted as part of weed game and being silently tolerated,
say somone cycled into to town in the rain to collect your package and decided as payent to take some out. that would usually be acceptable. To being seriously frowned upon e.g you cannot get weed anywhere and one of your cheepass "mates" knows a dealer your don't and having a monopoly links the draw bumping it heavily claiming the dealer ripped him off.
linking a draw for a pre determined amount of loot is a different thing entirely: to be a "bumper" one must take without prior agreement or take more than agreeed by the buyer.
my advice to cut out bumping; cut out the middle man- unless there absolutly trustworthy. And always go direct when you can, straight to the dealer also having a pair of scales helps alot, always weigh your draw to see how much bang you get your buck, even if you go direct, most dealers will try and bump you if they can.
Beware the bumper, he can take many forms.

After receiving the Z, going home and showing his mates it becomes apparent that he has been catted out, annoyed but with no one to turn too, he just has to grit his teeth and learn from the experience. After paying £190 pounds for round about 23.6g he ends up getting roughly 1.2g per £10 spent (an under average 10) in fact loosing 0.2g on each 10 and not achieving any saving at all that buying in bulk usually does. so yet again the bumber prevails The most venerable are the ignorant so before you start buying regularly... learn your shit.
