I love shopping for food at M&S (Haverfordwest) but it may be time to bring the checkouts up to speed Last week the till froze after all my shopping had been scanned, my son had taken the goods out to the car and I was told I would have to bring it all back and re-scan it - this I declined to do (I am 76 and have better things to do) This took over twenty minutes to rectify. This week my shopping totalled over £170 and even when beer was removed from the total was still far in excess of £140 but the till would not accept my coupon for £14, after ten minutes I gave up and paid the full amount. The staff were excellent but found it hard to deal with the problems with the tills and I am £14 short. Please sort this out.
