The parking volunteer waving in the rain might be the reason a nervous first-timer actually walks inside.

Whether somebody new stays or turns around is usually decided before they reach the door. Nerves attach to practical things: where to park, where to go, whether anyone expects you. Someone standing in the rain pointing at a space answers all three at once, and never learns they did. The decisive help in most situations is unglamorous and happens early.

Consider the room you already know your way around, a locker room, a youth group, a shift. Find whoever is there for the first time and tell them the two things nobody wrote down. Where to put their bag, and who to ask.
