Btw theres ways of messing with people where you can be polite and pleasant. Being aggressive  smug or rude or physically intimidating (walking in front of someone loaded down etc) isn't necessary. letting people know you don't want them around or you dislike them or just messing wirj them can be done in a civil manner. That's BUSINESS and that is understandable. Making things personal or all about your ego or cultural narcissism is not acceptable in any business activity or venture. By the very nature of business you are going to lose the game entirely if you keep on insisting on having no composure in a childish effort to make someone else lose theirs. Such is a culture and a people more accustomed to fast money and aggressive quick ways of aquiring TEMPORARY wealth.
