In theory it’s fairly simple…. If you don’t feel comfortable challenging someone for throwing coins, being racist, violent etc, take note of their seat number and Inform the club after.
If it is done enough times then the club has to take action. There are enough CCTV cameras at most grounds nowadays so be able to ID those responsible.
I haven’t been to an away game since the Hull semi and choose to sit in an area of the lane where the number of bellends is thankfully low.
Can’t imagine having to sit amongst a load of shit bags at an away game having had to fork out a fortune for the privilege.
I would find it really hard not to challenge them which would probably end in a feight.
Unfortunately, the vast majority of those who are or behave like, cunts, are not receptive to having it pointed out to them.
Chucking anything at a game (bog roll aside) - let alone coins is utterly despicable.
