You get pirates that do fair demands then you get the ass that try to pirate you 1 000 000 credits while you carrying water between 2 bases same system no way in hell will that be even anywhere a percentage of your profit any system.
I always thought fair price +/- would be like miners ,
Miners on average charge clients 10% of the total sales price to ore closest buy point if they guy want to cross half the universe to get better price for ore it would be transports pilot own choice but miners price normally around the same figure regardless where you ship the ore too which normally was up to 10% of the closest buy point if ore were baught in at 100$ for 1 ore the miner would normally charge 10$ for one ore.
Sometimes transports paid bonuses to miners for good faith or tnx for special mining request but that was totally spontanious.
i treated pirates the same the ones asking reasonable amount of $$$ for cargo and not extortionist traders i sometimes give bit extra for being nice but if the guy is a dick and ask you 1 000 000 $ for a load you make 50 000 profit on i jettison the cargo
shoot it to pieces tell him to go catch a fish and die with dignity
After effect if i see that pirate again online i log off that ship or log somewhere else in space and if it is a nuisance "dick" waiting for you every time same system same jump hole on every single time you cross it i log off for a week or two and tell FL see u when I'm in the mood for your bull $%^& again.
The only language "dicks" and "trolls" understand is 0% activity good luck hunting empty space.
