I was told titanium was bad for ear piercings?

When I got my cartilage pierced I wanted a titanium stud because it was the cheapest. I was at Piercing Pagoda (I know, not the best idea) and the woman working told me that they didn't pierce cartilage with titanium because it would almost definitely reject. Now I've just done some research on more piercings I want and I'm reading that titanium is one of the best things to pierce any cartilage with. Has anybody else been told this from Piercing Pagoda? I'm thinking she told me this so they would make more money which is completely bs. Or is there any truth behind this? Either way, not going back there again.
