I've started getting more requests from FC mates and sometimes people outside my FC to craft items for them. I've experienced a wide range of how people have approached me, from someone asking for full sets of equipment and not offering anything in return to people providing mats then tipping me during the final trade.
What is proper etiquette for approaching a crafter with a request? What is proper etiquette for a crafter to respond? I understand there are not definitive answers to these, but I would like to get some ideas from people with more experience in this.
