I am writing to protest in very strong terms against your decision to include animal derivatives in your chocolate bars, a decision I have just learned about through an article in The Guardian. This is completely gratuitous when all such products have previously been free of animal ingredients, and is tantamount to announcing that you do not care to retain the custom of the UK's millions of vegetarians. This helps to explain why I am now on another diet.
I am a long-term customer, a regular consumer of Snickers and Twix bars and your Snickers, Mars and Maltesers choc ices, and I will not be buying any more of these products until you announce that they are once again being made in compliance with vegetarian standards.
I take particular exception to the reported statement of your spokesman that "If the customer is an extremely strict vegetarian, then we are sorry the products are no longer suitable". Refusing to eat animal products is not "extremely strict" vegetarianism – it is the definition of vegetarianism. This ignorance on your part gives the impression of even greater indifference towards your former vegetarian customers.
(I should point out that, while I will be very grateful for feedback on this specific issue, I do NOT give my permission for you to use my contact details for any other purpose, and will be seriously annoyed if you do so.)
 This may not, therefore, be such a bad thing.
Honestly, though, in the name of Almighty God and all his terrapins and seraphim, where do they think they get off, doing this and then insisting that they're being "principled" by actually telling people about it?
In pleasanter news, I see Jeremy Paxman's started giving advanced notice of his facial expressions.
