Manners. There is nothing that you need or desire that would necessitate the abandonment of manners. This is how you show respect to your fellow man. It demonstrates that you are large of spirit and mind, and can enjoy the good fortune of others in a good bargain well-struck, and removes greed from the interaction of buyer, seller, and bystander.
If you do not admire a dealer because of traits that he displays, such as fast dealing, cheating, rude behavior, taking advantage of the ignorant, then show him a better way. Do this with admirable actions that would impress him and rekindle the dampened ashes of shame.
If you truly disdain his immature traits, then do not immediately adopt them as your own and display them in front of the dealer with the ill-fated hope of causing him to mend his ways. If you revert to childish manners, such as cutting into line, taking the last cookie, calling names in return, rolling on the floor in a kicking tantrum, tit-for-tat, or snatching a purchase from under the nose of a dealer, then you are merely using the dealer as an excuse to display your true bent of heart.
If you proclaim judgement upon the dealer and dispense justice with rude, selfish, immature behavior, thereby spoiling a potential transaction, beware - you have just issued judgement upon yourself for your own recent behavior (and bystanders will be wary of you, with just cause).
Let us be men, aspire to a set of ideals, a code of ethics, and a manner conduct that would lift our base composition, and act in such a way that we, and any others that may be watching, unnoticed, may respect ourselves .
