In the first lockdown in March all takeaways and fast food places where closed
They were not, big chains like Macdonald's KFC chose to shut, but they didn't have to.
Lots closed because they thought the lockdown was only going to be 3 weeks. When they realised it was going to be longer, it took them time to make adjustments such as designing websites, putting up screens, etc.
Our village fish and chip shop was closed for about 3 months because it was in tiny premises, where only 1 customer could be in at any time if keeping 2 metres away, and same with the staff behind the counter - they couldn't operate in a small area and keep 2 metres away from eachother.
They used the time wisely. They never had an online order system, but quickly got one made for them. The knocked a wall out between the kitchen/serving area to make it a larger open space so the staff could stay apart. They also had the builders in to make a sliding hatch where customers could collect their orders without going in. In June they re-opened for online ordering/click and collect only and have been busier than ever - the owner says his turnover is higher than it used to be when they allowed customer in to order & wait.
Our village bakery/pie/bacon bap shop closed because they thought they had to, according to the BBC and other media harping on about essential workers only etc. After a few weeks, they saw other fast food/takeway/food shops opening, so they did too, again took them a short while to get screens installed etc.
Certainly in our village, literally the one places open were the small supermarket and the post office. Everything else was closed, including the takeaways, pubs, restaurants, garage, butchers.
