Punters could be stopped from drinking at the bar at pubs as part of new proposals aimed at helping hospitality firms reopen on July 4.
Restrictions on the number of children in outdoor playing areas and patrols of smoking areas have also been put forward among potential measures touted to help sites meet coronavirus guidelines.
Trade group UKHospitality (UKH) has put forward the initial proposals alongside other industry leaders, in a 75-page draft document submitted to ministers.
Earlier this month, Boris Johnson said that some hospitality firms could be able to reopen from July 4 at the earliest in the Government's third phase of the lockdown.
