> That's fine if it's true, if not, why tell lies?

So that we can all skip this step:

> we tell them that water is fine

and jump directly to:

> we say fine and let them know that the meeting will be always open to them.

Good point. We'll change the meeting description to include this note about water (or anything else), this way we can skip the whole conversation and go straight to the meeting.

Isn't a better approach to pick types of meetings that don't have these outcast properties?

It's much easier to take the habits of early employees and call that "Company culture" without considering the reasoning or consequences. If Engineer #1 used to go on drinks on Wednesdays to cope with stress after the weekly release, 100 engineers later it becomes engrained as "company culture" to drink on Wednesdays at the same bar (which was on the way to his home) even though releases are now done on Thursdays and the bar is out of the way for most people.

Is there such a thing? Sometimes it's better to stick with what you like instead of spending days figuring out how to include everyone. We'll just adapt the meeting if we see someone doesn't fit.
