If you are in the First lounge in T5 then you can ask the customer service desk by the Champagne Bar. I don't think it makes any difference who you ask, and I don't think you will get very far unless there was any extenuating circumstances (such as delays / bad weather) or unless you are prepared to pay for the privilege. If you have checked luggage then you can only ask landside when you check your bags, airside is too late.
