While tuning the radio this morning (an unusual event in itself), I happened to catch a programme (on Radio 4!) about people from the Indian subcontinent running corner shops, and being open all hours.
It was very interesting, and it seems that the children of the shopkeepers are not going to continue the family businesses, preferring well-paid employment with evenings and weekends off and 2 or 3 holidays a year. One interviewee said that the shops were being bought up by newer immigrants from Turkey - "those Turkeys are going to be running the corner shops".
Wonderful mental picture - is that a packet of Paxo behind the counter?
