Transporting Cannabis in Public?

Hi, I’m having some trouble figuring out how to vape in public. For example, tonight I’m going out for dinner with my family, and I’d like to step out occasionally to vape, then head back in. It helps manage my anxiety so I can enjoy the evening. I’m also thinking about how to handle this for Christmas.

I’m curious—how do you transport your cannabis? I’ve been looking into tobacco tins for storing pre-ground CBD and THC, but I’d love to know what others use to carry it discreetly in public.
