Meticulous planners, oh hell yeah. It's painful the amount of paperwork and stuff that is associated with every action. You want to add a bunch of people to a social groups bank account.. you turn up with signed letter and their passports and the bank tells you "sorry but you could have nicked them, we can't help you, you'll have to bring them all in together"! Not always feasable and yet they won't flex.
Oh and raise a stink about something in a resteraunt over here and your as likely to get kicked out as placated. It depends upon how reasonable you are and they feel.
