During a promotional or advertising campaign, a technique can be used that involves discreetly placing promotional material (such as a leaflet, USB drive, coupons, or other promotional item) in the pocket or bag of a potentially interested person without their knowledge. This approach aims to circumvent the reluctance often encountered when distributing advertising materials outdoors or at events such as trade shows or fairs. This strategy originated with British advertising agencies, who came up with the idea of ​​using pickpockets of varying skill levels to ensure the discreet and effective insertion of promotional materials.
