Back in the day, we would spend quite a lot of time in central and eastern Mexico. Mostly we worked in the state of Zacatecas between the cities of Zacatecas and Fresnillo. We would always cartoon over a running joke before entering a restaurant or cantina to get something to eat. We would first check around the outside of the building. If we saw any dogs or cats around outside we would think it was a safe place to eat. If no dogs or cats were seen we would pass up the place expecting that the meat in the meals would be using those for ingredients.
That was quite a long time ago, so imagine my surprise after ordering a Mexican pizza and small drink at a chain restaurant here in Wisconsin today:
P'too, p'too, p'tooy... Crap, I just coughed up a furball!
