This creates a disincentive to use PC doctors or medics because those characters do not have any way to verify or otherwise confirm the discount.
To a certain extent, this can be dealt with ICly. A character can say something along the lies of "I get a discount. Hook me up." to the medical PC. That medical PC can then decide whether or not to charge less for services.
I thought it might be worth discussing here. As a player (OOCly) I want to interact with other PCs and use their services as often as possible. But there is no way my character (ICly) is going to "over pay" for services that he can get less expensively from an NPC.
What do the rest of you think?
If you have 'discount' perks, have you found that you prefer to get services from NPCs who respect those discounts?
If you are a service provider, would you extend the 'discount' to another PC? Would you even if you weren't sure exactly what the discount should be? (The perk is vaguely worded and gives a discount range, not an exact number)
