Is this correct? It will be against the law to have groups of more than 30 people, and against the law for businesses to reopen if they have been instructed to remain closed (beauty salons, gyms etc). But other than that the guidelines for businesses are just advice not actual law. So pubs for example have no actual legal requirement to provide table service only, to ask for customer contact details or to enforce any social distancing or covid related modifications when they reopen on 4th July?
