Just remembered, when I was at the Rome airport Hilton last year the maids were really nice and brought in a childs crib and made it up for us even though it was not their job (day shift was supposed to have done it apparently). I went to tip them and they refused it, I tried to insist but I could see they were getting offended (being Italian I can understannd why, I guess I forgot that I was not in the US).
