What Was Wrong?
The flight attendant that stopped Harriet’s entry walked towards her co-attendants and started whispering things to one another while looking at Harriet. Harriet being clueless and not knowing what is wrong felt nervous and awkward with the situation.
The Hesitation
Harriet was trying to figure out what she did wrong and what the flight attendants are discussing and why are they looking at her? She was then approached by the same attendant who stopped her. The flight attendant talked to Harriet and told her what the issue was. She went skeptical when she heard the issue from the attendant.
