/sci/, I need an explanation for a phenomenon that I keep seeing but don't understand.

I work in a hotel. Pic related is a simplified rendition of our ground floor lobby, which has the reception and breakfast area. The breakfast area has a massive glass door, and several open "windows" in the wall that shows the interior (tables, buffet, etc). It's basically impossible to take it for anything else than a restaurant, especially when there's people inside eating, with all the clinking of cutlery and such.

At least once per day, I will have a guest exit the elevator, look around the lobby, see the breakfast area in all its glory, then look to me and ask where the breakfast area is.

I do not fucking understand how this happens. How can you look at something so fucking obviously a restaurant, mere meters from where you're standing, with tonnes of people already inside eating, yet you still need confirmation that that is the place you need to go? Someone fucking explain this to me. I refuse to chalk it up to human stupidity, since I see plenty of retards find the restaurant without issues.
