I didn't know that titchy! Makes perfect sense though - you can do a lot of lay bets and only one is ever potentially going to lose.
I've had a bit of a shitshow today. Not only did I make qualifying losses of about £8 on two blooming horses, I also decided to punt a couple of free bets on the same horse (different bookies obvs) because the odds were SO short it just had to win, right?
It came second 
And then I didn't check Ladbrokes and missed the day two bet £20 get £10 offer.
Oh well, should keep my accounts in good working order, because I've been a right mug today
