You’re entering a brand new department store in your town. You’re looking for a new printer. You need nothing more than the thing to be able to print. So, reached the “Printers Department” (How convenient) and started looking at the printers. You have thousand of different brands, sizes, capabilities. You just need it to print, but you suddenly realized you’re going to spend money on the printer so you need at least one that lasts.
One of the new employee sees you and start telling you about the great capabilities of those expensive good-looking printers and tells you to “Buy this one, because it’s the best”. After a while, not yet decided, another employee approaches and begins talking about all the capabilities in general of the printers in stock. He asks you “what do you need?” just as the previous seller asked before telling you which one to buy. This guy instead starts showing you the ones he thinks will last longer (obviously expensive brands, for that is what they try to sell). He tells you that “Any of these are great”, and then leaves because the manager is looking for him.
