Thanks TB, really appreciate it.
It seems odd to me to have a smoking lounge at an airport which takes your lighting apparatus off you at security, so it does make sense to think there may be lighting apparatus in the lounge - perhaps they put out all the lighters that are taken off passengers
Will have a look when I get there tomorrow, if I luck out then I have a pack of nicotine gum that I bought for LHR.
Oh and I won't be using the cart either, I have a pair of legs that work perfectly and the exercise will do me good!
