Good on you for writing the letter. I hope it has the desired effect. My goodness - why is coffee such a big deal? Sometimes Mums who are looking after their own kid/s would be lucky to get a coffee break in three hours, and she's getting PAID to do it! I would imagine that she probably wouldn't be required legally to take a break until she'd done at least four hours work anyway. Good luck - I hope that something changes as a result of your letter.
