I enjoyed your conversation with yourself there.
You: What if you get something and discover it is bad or that you simply don't like it? Especially if you only took a relatively small amount to try it? Their absolutest statements seem a bit soup nazi.
Your response to yourself: I've been to several buffets where they claim they'll charge extra if you take more than you eat, but generally give leniency to people who just discover that something isn't to their taste. The rule is only applied to gross offenders. It's really not that exceptional, unless the enforcement is simply too strict.
And, that should have been the end of this thread right there.
