This DUmbass is unlikely to have ever been in Mexico, a nasty, nasty place with nasty, nasty food, unless you're an American, and can afford to eat in restaurants that rarely see a Mexican customer.
This DUmbass fits the quote someone recently used here in a sig line: "The idiot who praises with enthusiastic tone. / Every century but this and every country but his own."
(That verse did not come from the CalPig.)
You remind me about the tourists who would always flock to the roadside vendors of crabs and tacos across from Loquio Beach in PR. Then they would repent while praying to the porcelin goddess as they begged for forgiveness and Kaopectate. PR had some nasty parasites in addition to unsanitary food.
Zeitgeist travel hint: If the vendor does not look sanitary you might want to consider eating somewhere else.
Absorbing too much local color can leave you pale at the end of the day.
Just because the natives can eat it doesn't mean you can. This has nothing to do with the amount of 'heat' (often used to disguise bad meat, chicken, or fish ) a dish contains. Habinaro sauce does not kill parasites, burn off the hair on yer butt, maybe, but kill parasites, nope.
Bonus link for those interested in stomach parasites Yum!!Bon Appétit
BTW Has the Library Dick, Officer Bookman been informed of this??
