How can they bar you from the shops?
I have never placed a bet in any shop other that Greece but i would imagine you get an anonymous ticket...
YES...they just remember some faces and refuse to offer money back/ free bet's to some costumers!...from what I've seen!
I've had my photo send round shops (and it's not a pretty sight), not Paddy Power to my knowledge but Ladbrokes
and Coral, shop arbing was once very lucrative, I don't even bother now but some still do it, it was once the easiest
form of arbing, you didn't need any "new friends" every shop was like a new account so to speak.
p.s shouldn't have said barred, just £25 max bet usually, good as barred to an arber
