Right, I just go like this. Buying holy water..... I don't care who I get it from as long as I get it. (Paladins and devout clerics would probably be more strict) Temples, I'll enter almost all of em, with the exception of a few (unless I have good reason). Ie: Ilsare, the goddess who's child Ca'duz slaughtered. Well that's kinda a no brainer, I don't go there. I'd say clerics could be a bit loose as to which temple they enter and buy from, however I would say enemies of your god, are probably not going to want a cleric of that god hanging around.
