That one member of your club who refuses to go along with everyone else's ideas, or even compromise? He's unaccommodating. You can also say he's difficult or unhelpful.
Unaccommodating people make things hard for others, often by refusing to acquiesce to what other people want. An unaccommodating restaurant doesn't offer any vegetarian options and won't leave the olives out of your meal, even though you hate them. And an unaccommodating person might insist on meeting at her own house, refusing to meet halfway between your homes. Accommodating means "helpful or considerate." When you add the un- ("not") prefix, you get unaccommodating.
