I just happened to time my walk up to the front at a point where Scotswood Rd had no cars on it and nobody else walking around. My first time I was definitely a bit nervous.
That being said, just go for it. You’re over-thinking it. I’ve seen people walking in and out of all kinds of places and pay them no thought, nobody will care who you are or what you’re doing. Take a breath and just walk in – you’ll be incredibly glad you did once the door’s shut and you’re inside.
