The practice of granting special privileges or bonuses only to high ranking members of an organization by another high ranking official(s). This is done at the exclusion and ultimately at the expense of non ranking members. The term is obviously derived from complimentary mints placed on the pillows at upscale hotels for "honored" guests. These mints come from the aprons of the low-paid hotel employees.
