There's no mention about components in spellcasting service. I only found this:

> 
> **Acolyte Background**  
> 
>  A character possessing the acolyte background requesting spellcasting services at a temple of his or her faith may request one spell per day from the Spellcasting Services table *for free.*  
> 
>  The only cost paid for the spell is *the base price for the consumed material component, if any.*
> 
> 
> 

**Does the character need to provide components when using spellcasting service?** If not, then is providing component entitles the character to a discount to the service?
