McDonald's has made an effort to also include celiacs with the gluten free sandwich and then you ask for a coffee and, if I'm not careful, they give me one contaminated with barley, because they make both coffees come out of the same machine. The absurd thing is that the girl didn't even try to solve it (since I had already paid). When I explained to her that I have celiac disease and couldn't come into contact with traces of gluten, she shrugged. However I fell back on a tea, but obviously I won't go back.
