Cuban barkeeper serving drinks to tourists at hotel.
A Cuban barkeeper serves drinks to foreign tourists at the Hotel Nacional in Havana, February 25, 2005. Cuba has ordered its tourism workers to not accept tips from foreigners, in an effort to defend socialism that threatens to slash earnings of employees whose work provides Cuba's main source of hard currency. The order to reject gifts and limit other contact with foreigners was cast as a way to protect the purity of socialist values. REUTERS/Claudia Daut REUTERS CD
