Could this have been our very own Paul Papadimitriou!?

A man exploited the perks of business -class travel to feast for free 35 times in a year at Lufthansa's Munich airport lounge -- without ever taking off.
The man used the flexibility of the one-way fare to Zurich to repeatedly reschedule his travel plans after gaining access to food and drink. Lufthansa canceled the ticket after more than a year and refunded the price, only for the man to purchase a replacement.

Lufthansa didn't take kindly to it and took the man to court. 

The court ruled that lounge services are provided on the assumption that travelers will seek to fly, and ordered the man to pay Lufthansa 1,980 euros ($2,705), equal to about 55 euros per visit or more than twice the cost of the 744.46-euro ticket.
