There's a large population of people living in albergue transitorios as well. Pensions basically. Those 50 yr old waiters have also been doing it for 30 or 40 years, assuming they've stayed at the same restaurant -- and a lot of them do -- imagine how much the restaurant would have to pay in indemnizacion if they fired them -- job security is practically assured in this country once you've been at a company for so long.
