Please, don't let my argument stop you. There are plenty of Tytali in the Order. XD
But on a more serious tone:
Again, we are not talking about random magi meeting on the street (and I don't reccomend following a shady, unknown magus you just met in a dark alley who told you "come into my sanctum, I have a nice queen of vis with your name on it").
We are talking about either:
- someone you know on a personal basis who is asking you for help with a lab project;
- someone you don't know that well, but know enough about, and is paying you for a service.
I'd expect your personal view on how this would affect your reputation to be of higher relevance.
For example, I know people who won't stay alone in a room with the opposite sex because they just don't think it's proper. Heck, I know a guy who, instead of sending a text message to my wife when he needed an information from her, would either ask me to ask her, or ask his wife to ask mine.
So I can see a society where magi refrain from assisting others in the lab because of the involved social stigma. If the troupe want's to lean hard on that, assisting other magi can even merit a negative reputation (Lab Whor... Assistant (Hermetic)). If the troupe want's to play in a mature Order which grew past that, just ignore the bit on p. 103. If it wants to play in an Order which encourages collaboration make it a reason for a positive reputation.
Agreed, generaly. Maybe a better comparison would be with how people who grew up or went through hard situations generally enjoy trading stories and knowing they are not alone, or how people who are struggling with serious health issues flock together for mutual support.
Or, for a lighter tone, to compare with how we just get a little happy when we are traveling and meet someone from the same country, city. Or meeting anyone who has the slightest connection with us, whatever it might be.
This isn't going to make you instant buddies, and you'd still get pissed if you suddenly found any of those people inside your house without your knowledge... But after receiving an invitation you won't generally think "oh, this person is looking for an excuse to hurt me" unless your personal experiences left you with a deeply cynical view of the world.
If you are a magus and that's your case, you probably don't even live in a covenant.
