I think the idea with the tests is your default more so than situational responses. For instance, I'm an extrovert and an 3. When I went to Whole Foods and Starbucks it wasn't uncommon to see me laughing with employees or hugging someone. The same held true at Michael's, Jo-Ann's, and all my haunts.
Whether I'm in a familiar setting or not doesn't matter. Building a rapport is easy. I know how to connect and work a room. My communication skills are very strong. That's the primary reason I'm comfortable in environments that aren't diverse. I don't feel out of place.
