Strangely, I'm not - when I've paid such an over inflated price for the fizz I'd rather drink it. Besides, my girl like throw wouldn't get the bottle to the pitch from row U of WSU !
It really is a solution to an almost non-existent problem - and a solution that people can easily get around.
I rather like my FIZZY drink ... well ..... FIZZY ... and I drink it through out the match so need a bottle top on it. It's a pathetic policy regardless of other grounds and venues doing it. I'll continue to smuggle in bottle caps and PB can do not a thing about it.
Master WS and myself have had that as well. Not that it really matters as Master WS always has at least two spare caps with him .... equally I've been known to swipe the removed caps off the counter when the server goes to get our pies. A rather pointless policy really.
