well, if the agents do get themselves (along with CX the corporate) to kick out people who talks on the phone not in a designated area or sleep on sofas then it would (eventually) change.

i was in the PP lounge in IST and they have a sign saying not to put ur feet on table. people DO stop when staff points at the sign at them. For the 6 hours i was there its only the same ethnic group who does it, AND complies to the agent.

So i guess having a sign allows staff to take action easier. just like how the lounges in japan has signs of no mobile phone, and in reality they really mean not to talk on the phone.
