看标题大家发挥想象力，还是没有猜到为什么，其实原因非常简单也让人非常无语。
有不少人在自助交钱柜台（self check out）用狸猫换太子，自助交钱柜台买散装蔬菜（水果）的时候放在秤上自己在屏幕上选是什么菜，不少人选最便宜的菜种（比如说胡萝卜和洋葱）但实际上放在秤上的是贵的蔬菜水果（比如牛油果）。超市开始时候搞不清楚，为什么系统里卖出那么多胡萝卜但商店里的胡萝卜没少多少，后来弄明白了，这个问题的严重程度成了报纸新闻了，有些超市开始在自助交钱柜台装监控CCTV了。
看起来，不管是英国人，印度人，波兰人，中国人。。。。。。。，占小便宜的毛病不分人种啊。虽然我明白这个道理，但看了新闻还是感觉非常shocking的。
The great supermarket con: Shoppers are stealing expensive avocados by passing them off as carrots at self-service tills, criminologist claims

Sales of carrots have been soaring across the UK as self-checkout thieves pretend to buy the cheap vegetable while packing more expensive items such as avocados, a criminologist has claimed.
Carrots are often the cheapest vegetable by weight, meaning many Brits using self-checkout machines can save themselves money by lying about which item they are weighing when buying loose products. Brits seemingly bought 800 million more carrots last year compared to 2013.
Senior Criminology lecturer Emmeline Taylor, from City, University of London, told the Times: 'I was working with retailers to reduce shoplifting when one major supermarket discovered it had sold more carrots than it had ever had in stock.
Popular orange vegetable? Brits seemingly bought 800 million more carrots last year compared to 2013。'Puzzled by this development it looked into its inventories and found that in some cases customers were apparently purchasing 18kg of carrots in one go.
‘Unfortunately this wasn’t a sudden switch to healthy eating, it was an early sign of a new type of shoplifter.’ Britain has 50,000 self-service tills and more than £3billion worth of goods are estimated to be stolen through them every year.
Theft from these types of tills has become so common that one in four people have admitted to taking at least one item without paying。 Ms Taylor says that Brits committing ‘discount theft’ may not even view it as stealing.She added: ‘This behaviour is perceived as cheating the system or a way of “gamifying” an otherwise mundane routine.’
Ms Taylor refers to the thieves by the acronym SWIPERS, which stands for seemingly well-intentioned patrons engaging in routine shoplifting, and has placed them into four categories.
The categories are:
Accidental - shoppers who couldn’t get an item to scan or did not realise it hadn’t
Switchers - those who switch labels or say they are buying a different item when entering loose fruit or vegetables
Compensators - those who justify stealing by saying retailers earn enough money already
Frustrated - shoppers who justify stealing because of issues in store including damaged barcodes
