Maybe. But if a smartass comes in to where I work and tells me how wrong I am based on their shallow understanding of the domain I am likely to become frustrated. Jesperwe said they confronted this salesperson about the cables. They then lectured the salesperson on theory. There’s no indication a question was asked with an honest desire for the answer. When a conversation becomes a confrontation nuance is the first casualty. Jesperwe and the salesperson may have been participating in completely different conversations from their perspectives. Without more information I can’t draw a further conclusion beyond jesperwe participating in (or instigating!) a confrontation with a retail salesperson.
