"Having a conversation with someone from a different social class may require more brain power than speaking to someone with a similar background. Participants were not told if someone was from a poorer or more affluent background, but worked it out based on cues such as appearance, mannerisms and how well-spoken the other person was."

Considering how complex humans are, this anxiety seems intuitive ('If we meet someone unfamiliar ... the brain has to work differently to process that successfully"). And the shorter amount of time to socially bond creates pressure that can lead to anxiety.
Interestingly, those without significant anxiety may have less desire to bond in that artificial social moment. In real life, recognition of class difference might automatically dissuade meaningful interaction. However, a participant in such study may feel obligated to be productive in the interaction, therefore anxious.
Those who would be anxious in real life would probably escape to their cell phone, or reading material, or snooze.
