Like a lot of people, I did my time at McDonald’s, working at the Opera House McDonald’s restaurant here in San Francisco the summer before I started college. I am quite convinced that taking advantage of the free, unlimited access to soda was directly responsible for some serious dental issues I suffered subsequently. I don’t blame the company, however; it was completely my own fault. I should have known the damage excessive amounts of soda could do to my teeth and, perhaps more importantly, no one forced me to drink the soda. One store manager in Brazil, however, faced a different set of circumstances.
