Slightly off.topic but my snobbery of sorts is that I have boycotted Mr Kipling products because of their money over morals attitude to re-using factory methods of egg production and the dishonesty with which they've gone about it.
They made a fanfare of going free range a few years ago, TV advertising, et al, all chickens having access to the outside.
This didn't last long and they very quietly reverted cheaper indoor means without mentioning it to anyone.
They've been forced to disclose the downgrading and change to their ethical statements only by customers such as us and welfare organisations spotting and challenging them & publicly embarrassing them into it.
