I am not familiar with ground rules at other sports, can you nip out for a fag at old Trafford or etihad or reebok etc?

Varies from ground to ground and depends on how the place is set up, but the vast, vast majority is no.

No you can’t nip out, but you experience very foggy toilets at those grounds, well done to the LSV stewards for ensuring it’s not the same at LSV.

Being a non-smoker I’m amazed how some sleep, work or fly if they can’t go two hours without a fag.

Best way to give up smoking is try Nicotine Patches , try lighting one of them , my old mum went down from Smoking 40 a day to 2 a day , mind you they were 3 ft long .

In the days of electric cogs there's no need for anyone needing to nip out.
