Don't listen to these folk, they just want to get you in bother as you sail through the doors looking straight ahead.
I'm there both days and if you send me off the £50 entrance money ahead of the game, I'll make sure you get your 10% discount. In fact I'll put your name on it and hand it to the barman for safekeeping just in case we miss each other.
You can never be too careful in a big city you know!
