Does this make any sense?

So I'm watching a show on the Travel Channel about hambugers and the owner says this: "When a customer walks in the door, we always say hello to them so that they know that they aren't like everyone else."
While I understand what the true meaning was, what was actually said makes no sense. If you do in fact say 'Hello' to everyone that comes in, then you ARE treating each and every customer like each and every other customer. Therefore, you ARE like everyone else.
Its a bit like the transitive property.
