As we live rurally - only half an hour from a major city - we can't get take aways let alone delivery! And even in rural towns with plenty of take away options delivery is by small car usually. So this isn't anything I can speak to, though it occurs to me that Britain seems to complain about immigration a lot unless migrants are doing useful things like delivering their food and Amazon orders, and that migrant delivery cyclists must keep pretty fit...

Anything ID/surveillance worries me somewhat, but perhaps the horse has bolted somewhat there.
