I am that sad old dear who also checks that the speciprices/ discount/ bogof has registered. If I am wrong I have no embarrassment in apologising. Many years ago in the days when £50 for a supermarket shop was really pushing the boat out DH came back from Sainsburys having spent over £80
I checked the till receipt and saw that sausages instead of coming up at 50p or so had gone through at over £5.00 a lb!! Quick phone call got me my refund next time I was there.
