I've already been in the lounge, I just left to go to the Duty Free...
About a month ago I visited the Air Canada Lounge LHR and whilst we were waiting to get our Boarding Passes checked a gentleman walked straight past the desk and said "I've already been in the lounge, I just nipped out to the duty free". The lounge was busy and I was a bit annoyed that he wasn't stopped or questioned, He had no luggage labels on his bag to detail that he was a frequent flyer or any status?
Have you witnessed or seen anyone sneak into the lounge or not bother about registering with the Lounge Attendants?
