McDonalds have taken the step of publishing and answering customer queries on the website; Make up your own mind. Looking at the questions answered section, it’s amusing how many urban myths people seem to readily believe.
For example; “does your milkshake contain dogs lips?”
Never heard that one, myself, but it sounds too ridiculous to be true in the first place. I mean, just where is their giant dog lip processing plant based? Do confused dogs roam the surrounding area sans-lips, unable to remember what happened to them the night before, and curious as to why they can no longer whistle “there’s nothing quite like a McDonalds.“?
