Alas even those in existence still often can't be as flexible as required to provide fuel \ services as required, particularly when operating at night or weekends. Almost invariably this is not through mil airfield's want of trying.
Limited resources show their hand frequently whether it be airfield opening hours (ATC capacity), VAS availability etc. One exception to a helpful approach, however, is my personal favourite "we only refuel the reds".
On the plus side, many civvi places are keen to offer up a bacon sandwich to the crew, so it isn't all bad news!
