I dont care if hes lying about laying out £300 on that bet. Fair play to him if he only put £30 on it i never thought that bet would come in well done. If he is lying though he just wants people to think hes cakeholed and £300 is nothing to lay out on a bet me personally i wouldnt feel comfortable laying out more than a score
If he's lying and put nothing on it he'd feel a right numpty. No one wants to tip a 30/1 double and bottle backing it.
Hard to believe he tipped it up and didn't put anything on it, as for the bet slip, i don't know how to take screen shots either and even if i did i wouldn't be arsed to. The sheer fact he made a thread tipping the bet is all the evidence we need.
