If you don’t tell the people why you are leaving, they don’t know what is going on. And this applies to businesses it applies to stores it applies to companies. It even applies to social media accounts. It even applies to your friends and family.
If you tell people why you are leaving, at least they can make a decision if they want to change or not. If the company or whatever is seeing less people coming in, but nobody will say why they’re leaving. How can they make the change?
There’s no realistic way that a manager or a host or the owner of a business or whatever could realistically ask every single person who comes through the door hey are you happy? Are you coming back? Is there anything we should change? That’s not real.
If you aren’t happy and you don’t say what is making you unhappy. Then that’s on you.
Not the business or the social media site or whatever.
They can’t read minds.
I only really see that statement applying to only specific situations such as:
Social media - like a big facebook group for example, where people don’t really know each other personally. No one will really care if you leave unless you’re a moderator or popular member that everyone recognizes.
Big gatherings or parties - If it’s a big party and you don’t know everyone or you’re not really personally acquainted to the host, I don’t really think it’s necessary to announce you’re leaving.
