"If we get this under control, we will be able to resume opening up, to the vast majority of people doing the right thing, I again say thank you very much. If you are out there just breaking the rules and betting you won't get caught, the odds are not good... you will get fined.
(Restrictions) will not be around any longer than is necessary if everyone follows the rules."
