Mexicans are nasty. 

At my last company I often had to travel to constructions sites for inspections/evaluations. Mexican workers all over the place. Every time I went to take a piss in a porta-potty the shit in the tank wasn’t like any shit I’ve ever seen - it looked like someone dumped a 10 gallon can of beans in mud. Now I know why they call them beaners - it’s all they fucking eat.
