I've always clapped both teams through and walked through myself at the end.
Just thought this was normal.
You will get some who will ignore you, some shake your hand/ pat your shoulder/ cheers ref.
Was AR last week and my ref colleague clapped both teams off but didn't walk through, said he never has.
It seems these days that most teams form ad hoc merrygo round and shake hands immediately after the final whistle and you will always get the odd player who deliberately avoids you but that's their choice but there has and hopefully always will be the tunnel as you leave the pitch.
What's people's thoughts?
