I would say it’s OK as long as you are vigilant not to talk with them, nor give them eye contact, nor any friendly or welcoming body motions (like don’t face in their direction).
Think of it like animals of prey waiting for a chance to attack. If they see a sign of emotional weakness or your guard down, they will feel that they have the opportunity to attack.
They = wolves
You = sheep
Tsniut = sheppard
