Some pertinent information:
1. The person was wearing a tie.
2. My friend claims that the person was, shall we say, "chesty" in profile when he/she walked by our table.
3. The person was at first sitting beside a girl, but then the rest of their (?) family joined them.
4. The person looked somewhat alternative in dress, making the ambiguity even more challenging.
So, with those clues and this picture, go forth! Opine! Settle our debate.
