I am always impressed by the insane over the top work ethic that Mexican Migrants have. I hired a new maid to clean my home, she was half the price of most of the other ones on the site, which I like because then I can give very generous tips... Not knowing I was going to tip well she even brings her sister at no extra cost (keep in mind they are working hourly here)...
Best cleaning job I ever saw, took half the time because I had an extra person for free, and at half the price to boot. Can't wait till they see the 200% tip I gave them :)
