The usual annoyance of not being able to lay
So far no issues that I can think of. The usual annoyance of not being able to lay a double on my own team (the bookies logic is that if Liverpool win The Premier League then they are more likely to win The Champions League. For a start that is not so but even if that I accept that logic then just offer me a price that reflects that).
At the end of the day I don't bet with this bookmakers often because they don't offer the best prices.
