Just returned from a long visit to Mexico and noticed an anomaly. In currency, the decimal mark in numbers was used as in American English such as $49,000.00.
However on items such as soda cans, these were mark as 1,5 L, as in French. So does Mexico follow the U.S. example or that of continental Europe? I DID some some items were bilingual in Spanish and Portuguese. So I expect this could play into it.
