Nothing is so great an example of bad manners as flattery. If you flatter all the company, you please none; If you flatter only one or two, you offend the rest. Jonathan Swift
It strikes me as bad manners for a magazine to accept one of my advertisements and then attack it editorially - like inviting a man to dinner then spitting in his eye. David Ogilvy
