Why are millennial men so immature and disrespectful?

Today a guy my same age threw the recipe at me and I stop to prove I had paid for a cake for a church gathering. I wasn't rude to the guy or anything I walk just like any other customers I showed him and told him Hi I am here to pick up a cake. This guy I mean he had no business skill what so ever had the nerved to throw the recipient at me. I ask to speak with his manager and he refused called me a fat Karen and laughed. I tough at first he was the manager turns out he was just an employee 31 year old looser who didn't do carp with his life after highschool but still has the mindset of a 10 year old. Another employee had to called the manager. I just can't why are millennial men like this? Why are millennial men a bunch of spoiled men child's? I don't understand you will never see this behavior in a generation X men.
