No member shall vote on any question in which he is financially interested (other than the common public interest) or any question concerning his own official conduct, but on all other questions each member of the council who shall be recorded as present shall vote on all questions decided by the council. Any citizen or taxpayer of the city shall have access to the minutes and records of all regular and special meetings of the council at all reasonable times during regular office hours of the city clerk.
