Trouble with most Uk shops is that they aren't sh*tty enough with their staff or open for long enough. Got to be open from 08.30 until 20.00 and have your staff on triple split shifts if you want to make money nowadays. 9 to 5 with and hour for lunch is so last century. Sainsburys have right idea, went in one near Folkestone the other day, 6.30 am until about 9 in the evening, they're not struggling.
