Takeaways didn't have to close. They were quite busy but totally bombarded by "I work in x throughout covid, can you give me anything free?" Well.... So were these people! And worse abuse than usual. Want to hear some creative racist/xenophobic insults? Be a not white/non british takeaway worker.... But that's a different rant.
Re the "support" to close during covid. Nowhere near enough so who could stayed open at least part of the time (like restaurants doing takeaway).
