It is not as easy to communicate across tables with close friends. Certaninly I feel completely locked out of dropping by tables and having a chat with everyone - particularly at the final tables.
I would say the behaviour at the table isn"t very good at the moment.... asked two people on our table tonight to "play nice", think their quotes were " up yours" and "eat s...". Think APAT barred people from playing last year for less. 
Completly agree.
One of the great things about APAT is the friendly nature of the members.
How many other tourneys are there where players clap every exit?
I think warnings should be issued for abuse/swearing at the table and a ban for frequent offenders. No matter how bad a beat it is, there is no excuse fior abuse.
I realise this is hard to police but we could at least try and stand up for APAT and what it stands for when we come accross these people.
