Are they trying to get attention?

My friend and I often go to the same restaurant, and we see the same group of guys there. We dress comfortably—no makeup, loose shirts, and hats. We're not trying to look attractive or stand out.

But every time, a group of guys ends up sitting behind us. They could sit face-to-face with each other, but instead, they choose to sit side by side, facing us. This happens every time.

They don’t say anything, but they stare at us when we notice them. What do you think is going on?
