Uniforms often have a powerful impact on people even if they don’t realize it. If you are a member of a group or profession that is associated with a specific type of uniform and you have the opportunity to wear it to a bartering session, do so. The uniforms of law enforcement officers, medical professionals, firefighters, and individuals in the military may positively impact people’s perception of you. Many people want to thank individuals for their service, so give them the opportunity to express their gratitude with a discounted price. Just think about how many restaurants businesses and organizations offer discounts for uniformed officers and military.
