Is it wrong or considered pooretiquette to bring your own equipment/accessories to have the pro shop to install for you?

Obviously, they would get paid for their timeon theinstalation.

I am considered by my co-workers to be a tight ass, and I don't want to pay pro shop prices if I can pick up equipment for less at a different store or e-bay.

I don't have the necessary equipment or knowledge to do some things on my own. Thus requiring the assistance of the pros.
