Query: Unethical Advice

In the section "Veganism 101" regarding eating in restaurants the authors write:"Tell your server that you are "allergic" to the items listed and ask them to inform the chef. It may be a tiny lie to tell them that you're allergic, but allergies make resturants stop and listen."While I clearly support veganism - I find this advice offensive and dangerous.I'd like to return the book.I'm writing the publisher.BTW - I have the 2007 version - 13th printing. There is now an index.
