I interpreted it as they were stuck on the tarmac for a long time. People were getting dehydrated and asked for water. The FA’s refused to serve drinks on the tarmac. Passengers said “fuck it this is a health issue I’ll just get it from the galley myself”. The FA’s threatened that anyone who did that would be arrested.

Passengers only options were to either deal with the dehydration or declare an actual emergency and get official medical transport off of the plane to an ER and deal with whatever bills/consequences that might generate.
