my own interpretation of events
Vincent was your boss. He was a little odd, pretty cold to you, but you were his only waiter. You did a lot at his restaurant, but did it well, at least according to him a while ago. Today it was raining, and pretty hard. You didn't exactly have a car, so you walked to the restaurant in the rain, your uniform tucked away into your bag so it didn't get soaked. You opened the door and hesitated a while, trying to figure out how to go inside without tracking water all over the place. Eventually you decided on coming in through the back, since the kitchen was tile and if you didn't get it clean before people started coming in they wouldn't see it. The chefs were preparing their stations and Vincent did not seem amused when he saw you.
"..." The man walked up to you, staring down at you coldly. He sighed and gestured to you. "Did you not have an umbrella? You look like a wet dog." He barely waited for you to respond, rolling his eyes. "That's what they're for. I'm giving you mine for the walk home so you don't ruin your apartment." The chef huffed a little and turned away, and returned with a towel a while later. He put it on your head and started to scrub your hair dry with it. "I hope you have your uniform. Dry yourself off and then go change." He did not give you the towel.
