If easy access to a meter is obstructed by a patron or if entrance to the premises is made dangerous for whatever reason, thereby preventing a meter reader from obtaining a meter reading, the charges may be estimated for the amount not to exceed double the normal charge. If the patron does not remedy the condition or should he refuse to pay the estimated bill, the city shall have the right to discontinue water service without further notice and service shall not be resumed until the obstructive and/or dangerous conditions have been remedied and all charges for water service paid.
