I don't use crappy corner stores, so it literally matters nought for me, i'm happily spending my money in huge conglomerates so that the continued death sentence for small business continues.
I don't do my full weekly shop in them but they are handy for the odd item. Why get in the car and drive other side of town to the supermarket then walk from one end of the store to the other and then drive back again. Takes under a minute to walk to the nearest corner shop.
And it doesn't matter if its against the law to not accept cards under a certain amount now, if the 6'2 Sikh built like a brick **** house behind the counter says no then he mean no!
