Dun Scaith and people asking to pass

[Mirakumi]

So I ran the whole day on Dun Scaith on Saturday hoping to finally get the healing body and was met constantly back to back with people asking to pass on gear. Now I was in full 250s at the time with the class that I brought - so I did need them too.

But it kind of gets wearing to pass, and then come in and the next person needs it somehow because they've been at it for years and im sorry that I brought my alternate job SCH when I (main bard). then the next person. next person. (I was like meh, stormblood but I can only take it so many times - besides being out rolled multiple times by higher geared for seals so I finally just kept my roll and was called an ass for it.

What is a polite way to explain that you don't want to pass on gear? Because you've passed multiple other times for it.
