You put on the uniform, and you become invisible until someone is upset with you for whatever reason like you've blocked traffic with your truck, or you're taking a break too close to their home, or you're drinking coffee in their diner, and they will come and scorn you, and tell you that they don't want you anywhere near them.
Te pones el uniforme, y te vuelves invisible hasta que alguien se enoje contigo por alguna razón como que bloqueas el tráfico con tu camión, o estás tomando un descanso muy cerca de sus casas, o estás tomando un café en su cafetería y se acercan y te desprecian, y te dicen que no quieren que te les acerques.
