I've just had an email from Tesco saying older people can shop there from 9am to 10am as priority customers, and that everyone will now be limited to a maximum of three items of any one line. This should stop the greedy grabbers and stockpilers.
We mostly shop at Morrisons, and I don't know what their policy might be. The branch we use (in the sticks) is always crammed with old wrinklies anyway, many arriving in special minibuses complete with their wheelchairs/walkers/shopping trolleys etc. We might go there tomorrow morning. Hope I shan't be arrested for being in public over the age of seventy! My husband looks about forty though, so I'll have to explain he's my chauffeur/carer hee hee.
