According to new research 73% of consumers find automated tills the most infuriating part of shopping for food. Whilst the self-scanning machines have been introduced to most supermarkets as a method of easing the stress of a weekly shop, it appears that for a large majority of the British public, they are doing quite the opposite. Although they may ease queue congestion, the anger they invoke when they fail to work properly is turning a lot of people off using them altogether. Marks & Spencer was the first British retailer to pilot self-service tills in a few stores back in 2002, and since then the practice has been adopted by the majority of the bigger chains, including Tesco, Asda and Sainsbury's. However, independent retailers are viewing the findings as further proof that customers favour face-to-face contact over automated service.
