Val will shift herself into an older gentileman once she finds a quite place to do so. She'll put the scarf under her vest like a kerchief, and roll down her pants, resulting in a more business dress style. She'll tun in her shirt a bit more to remove any slack as well.
Then she will try to gather some sort of official looking paper about that warehouse.
THEN she will enter the locksmith's shop.
"Excuse me sir, one of my assistant's misplaced the key to my warehouse, and I was hoping you might be able to help me get in. I was told you were one of the best locksmith's in town."
