That culture comes from a lack of process and experience of large organizations. The second that a team grows beyond 7 people it has grown beyond the direct control of any one person and the culture takes on a life of it's own. If not addressed early in growth, issues typically spiral and are either not caught or are allowed to exist out of a perceived necessity.

Small organizations are nimble so they do not need to formalize cultural and HR processes in the same way that large organizations do. If the leader sees something they don't like, they address it. It isn't just about basic respect. We all bring our own cultural issues to an organization. A lack of professionalism comes hand in hand with smaller creative organizations. That's what makes them entertaining. It also enables the toxic tendencies of some people as they are allowed to slip in and as the pressure builds. Don't confuse professionalism with respect.

These things don't happen immediately either. It happens over time as people get tired and impatient so they are not on their best behavior. We all go through a storming process. That's when toxic culture can set in if good lower level leadership doesn't catch and address it. That takes training and a formal approach to organizational structure, not just production processes.
