It is interesting how many people immediately jump to a jaded, negative explanation, missing a rather obvious alternative: what if the guests are just curious?

It is interesting how many people immediately jump to a jaded, negative explanation, missing a rather obvious alternative: what if the guests are just curious? That would, at the very least, be my case. Some pizzerias do have an "open oven", and seeing the cook preparing the pizza is a nice show of good workmanship. It is not that different from watching a blacksmith on a fair hammering out a horseshoe. We live in an age of industrial production; artisans are becoming rarer. In a similar vein, some new train sets in Europe actually have a transparent engineer cockpit, so that the passengers can see how the track looks like when underway. Again, this is meant as a satisfaction of natural human curiosity, not some elaborate class scheme to humiliate the engineer, who is a valuable employee.
