There's a lot of differences between the United States and Mexico - average tan levels of it's citizens, the overwhelming need of Mexican salesman to give tourists "the best prices, almost free" - and offer these blessings repeatedly - regardless of the product or the prospective consumer's level of interest, and the labeling on their products. The US is much more politically correct in their verbiage of warnings. Take for example a warning label on your average pack of cigarettes in the US - it reads "Warning: The Surgeon General Has Determined that Cigarette Smoking is Dangerous to Your Health". Now look at the Mexican variant - it's much more, umm, to the point :)
