I look at it a different way - if I'm going to eat turkey, or any other meat for that matter, I want to know that the animals/birds concerned have been treated in a humane way throughout their lives and I'm prepared to pay a little bit more if that means the supermarket, butcher or farm shop can guarantee that.
I don't want my purchase to condone bad treatment of any animal and I'd rather eat a little less meat and pay a little more to ensure that.
I used to have a smallholding and reared our own meat, lamb, beef, goat meat, pork and poultry. I knew that the animals were treated well and that when the time came for them to go to the abbattoir, I knew the men who worked there, we took the animals there ourselves and we know that they weren't unduly stressed or frightened. Not only were our consciences clear but we benefited from really tender meat (adrenalin can toughen meat). The Michaelmas and Christmas geese I killed, plucked and dressed myself.
To me the Waitrose advertisement shows me that the turkeys in question have been treated well throughout their lives. I would rather buy one of those than an anonymous frozen lump.
I've overheard people in the supermarket say, "I can't eat anything that looks as if it was alive" or "I can't eat anything with a bone in 'cos it reminds me it was an animal". I'd have respect for them if they were vegetarians, but to buy meat and pretend to yourself it was never alive, and what is more, not care how it was treated seems wrong to me.
I think the Waitrose advert is honest and I applaud it.
Hope that doesn't offend anyone
