A young lady has opened a food truck near my neighborhood. The first time I went there I couldn't see a menu anywhere on the outside of the food truck and while I was looking the window opened up.

Two young ladies were just looking at me while I was looking for the menu. I said "This is my first time here. Where is the menu?". They continue to stare at me and they haven't said a word. I say "Do. You. Have. A. Menu.?". One of them says "It's on Instagram" and just looks at me. I tell them "I don't have my phone with me. Do you have a physical menu that I can look at?. Blank stares from both of them and I ask again "Do you not have a physical menu that I can look at?".

One of them hands me a dirty piece of paper that is a menu printed on a piece of paper. As soon as she hands me the menu she immediately says "What would you like to order?" (The first words they spoke to me in this situation). I stare at her while I'm still grabbing the menu from her hand and I say "You've been here the entire time I've been at your food truck and you know I have been trying to find the menu because I told you this is my first time here. Do you think I know what you serve without looking at the menu first?". She looks at me and says "Like you do or don't want to order food?". "I was going to order food but after this crazy social interaction I'm just going to go home and make myself something to eat".

It was literally one of the dumbest experiences of my life and these two 20 something year old women thought that is how they are supposed to interact with their customers. The crazy part is there food truck is still in business.

I believe the real reason people are so upset about the so called "gen Z stare" is less about the act itself and more about what it symbolizes.
The high-trust, cordial, welcoming society people knew from up until the early 2010s is gone and the young generations tasked themselves with delivering this cold message.
Asking low wage workers to cheer their customers is offensive, they are not paid enough to do that, all you get back is a passive-aggressive blank stare.
Being less than two meters away from a stranger is a violation of their personal space, just like the lockdowns taught them.
Interacting with strangers in general is a no-go: no more free gratitude, chitchatting and other spontaneous interactions in the name of a "cordiality" nobody cares about anymore.
The era of undeserved, unconditional wholeheartedness is over and zoomers are letting everyone know.

Does this phenomenon happen in your country?
