When I was a young man my mother taught me to tip and tip well. But that doesn't include, to me, anyone and everyone. You carry my bags you get a tip. You clean my room you get tipped, especially if I get extra coffee for the room. The cocktail waitress, she too is tipped. If the desk clerk pays attention to me, looks me in the eye while speaking and shows true interest in making me feel like a valued guest then he or she will get tipped. I feel the "tips are expected" idea by those who receive them really hurts those who deserve a tip as recognition for a job well done and above what is expected of them. So during hand pay's I thank the person who pays me and tip the slot attendant that wished me luck and another tip for the cocktail waitress who kept me from going thirsty. That's the way I roll.
