The Grand Hyatt Hotel in San Antonio has this sign on guest floors: "Be considerate of other guest between 10 pm. and 6 am." I guess you can treat them like dirt the rest of the time. ... This announcement was made on an American Airlines flight as I was traveling back from San Antonio. "If there's anything we can do to make you more comfortable, you can ask. But don't kid yourself. We can't." (OK, so I added some words.)
