Once again , the 2 , 000 + year old maxim holds true . " caveat emptor " - - let the buyer beware 再一次提醒，有2000多年历史的老准则保持着真理。 “顾客留心(货物出门概不退换) ” ?让顾客小心。

Example : in the 19th century there were few laws protecting american consumers , and so the slogan of the marketplace was caveat emptor 19世纪保护美国消费者的法律很少，因此市场的流行口号是“商品售出，概不退换” 。

Lawsuits brought because of falling share prices make a mockery of both the principle of caveat emptor and the honourable new york tradition of never giving a sucker an even break 由于股票价格下跌导致的诉讼，给了股市有风险，入市须谨慎（原意为顾客留心，货物出门概不退换，由买主自行当心）原则以及从不给行将就木的企业一根救命稻草的纽约传统以极大的讽刺。
