P99 Group Etiquette for drops?

[zaneosak]

After playing P99 for a few months at a time with like 8 different breaks over 2 years I am getting to the point where I will be getting groups that actually camp rare spawns with item drops. What is the etiquette on P99 for drops with monetary value? Everybody rolls for the plat or do people that actually want the item get it? I remember a combination back in the day on these rules but that was mainly because everybody was in shit gear. I am assuming its just free roll but was curious.

I am talking about camps like Lower Guk for example.
Thanks for any info.
