There are two attitudes:
a) Strict adherence to the exact wording of the rule, regardless of the actual intention behind it. This is useful for people like administrators who want to get rid of you and traffic police looking for bribes.
b) Infinite flexibility and creative interpretation. Useful for administrators who want to get rid of you and driving in Sofia traffic.
Which attitude you adopt depends entirely on what benefits you the most at that particular moment. It’s also quite normal to use b) while simultaneously using a) to criticise other people for doing the same thing as you.
