Someone’s painted a box on the ground beneath a cash machine. For demarcation against intrusion. For the protection of the PIN. For the exclusion of undesirables. The slot for the card has a green light flashing on/off, begging for custom. A man and a woman approach. I can hear the click of the slot opening. The woman is pressing the buttons, the man stands in the box as well. They leave. The light starts flashing again. The screen too is busy. It advertises Halifax financial services and exhorts users to protect against fraud or theft. In the corner of the box, dropped by a left hand as the right worked the machine is the torn, curled peel of a satsuma. 9.43 am.
