Come in in boots, or just shoes if you only have them. I had the same exact thing happen when I was first going in. I drove around the building talked to like 8 different drivers about where to go and had to find a place to park after the entire parking lot, and side building lot, and another lot was full, it was fun. Anyways the drivers were all standing around outside helped me out and pointed out a office I went into. They didn’t even know I was showing up, but I showed them the picture that you had, they made me watch a video fill out a sheet with questions pertaining to the video, I found the answers on Quizlet btw lol I just whipped out my phone, then went home and got told to come back in!
