Hence, the world we live in. Where people DEMAND a tip. A tip is only supposed to be earned if the customer deems that the supplier did an exemplary job and should be further compensated for something. I say FURTHER compensated, because you should already feel a sense of satisfaction just helping a peer out to acquire a relic weapon he/she most likely spent a ton of time to get the mats for.

Wow, switch servers? If you give me mats I will craft anything you need free of charge. I won't turn down a tip, but I sure as shit won't demand one either.
