A cook who refused to taste the food he cooked but served it to others!

It should not be acceptable for some one to advocate or defend something they are ashamed of. A marketeer who is ashamed of his product should be the worst hypocrite that ever existed. If you market a product so vigorously and persuasively yet you can not taste it then the product contains poison.
a lecturer who lectures a subject he never leaned is the worst of hypocrites.

A cook who refuses to taste the food they have cooked should be treated with suspicion and expelled. Why would you cook food you can not taste if there is no hidden agenda?
You can not drive a car from the outside! if a driver tells you that he will be driving by remote, then better disembark from the bus before you die.
A man speaks so vehemently in support of sodomy but himself can not taste means he is a hypocrite.
