I think it certainly helps, I would not have got my current opportunity had it not been for my cabin crew experience. I felt it gave me a lot of strong examples for competency based interviews, and also it was the best job I could have ever had as an 18 year old, I thoroughly enjoyed my time doing it and do often miss it.
I would echo fa2fi's comments. Having the right attitude is imperative for success, certainly do not think it is below you as that attitude will become obvious to your colleagues and you will become unpopular very quickly. Although I was never a qualified pilot whilst flying as crew so my perspective may be a little different. There were a fair few qualified guys and girls flying as crew, most were fine and a pleasure to work with. I know a few FOs and Captains where I was started as crew.
Good luck
