There is a far better way for Sainsbury’s to cut shoplifting than using facial recognition tech (Report, 2 September). It is simply to employ more staff to serve at the checkouts rather than increasing the use of self-service terminals. Last time we went to the Sainsbury’s Whitechapel store, there were no staffed checkouts at all and no floor manager to complain to, just self-service tills and one harassed member of staff trying to keep an eye on things.

• Regarding Zoe Williams’ dealings at her local tip (2 September), if the recycling centre isn’t interested in old but working computers or monitors, how about asking your local school? Our local primary was happy to take my old but fully working Apple iMac and Mac mini.
