It does has other effects that they may be interested in, at least if they require that the person in the queue actually be the attendee. Forcing people to stand in line in order to attend an event means that only those who are willing to spend time rather than money will be able to go. This has effects on the type of person who ends up in the crowd - arguably people who on average are more interested in the event, even relative to a lottery solution since that would give you a more random distribution of folks along the axes of access to time / money. That said, it does come at a cost. Edit: I'm realizing now that you may have been more focused on retail than events, in which case I suppose the identity verification option that I'm discussing I admit seems a bit stranger / less relevant.
