B&q Southend on sea - Coronavirus period
For the uninitiated, you queue outside as with other shops. Keep 2 m distance in store, with some aisles closed off. Only one way to check outs. Place your goods on floor in front of till that is available, then step back to the yellow line. If you have trolley, place trolley in front of til. Wait for tiller to scan items. Then step forward to pay contactless with card. Don’t know if there is limit to card payment, as I only bought a few inexpensive essentials.
