I've no idea what you tip a baggage person. If the service was poor, you should probably inform the manager and not feel obligated to tip. If you are at a restaurant and wish to purchase an alcoholic beverage, the waitperson may require that you produce proof that you are of legal drinking age. Some establishments require that their staff check the identification of people, even if they look to be in the late twenties or thirties. If you're going out to drink or looking to go out dancing, save yourself the headache and carry proof of your age.
People love to complain about the weather.
It gets really windy during spring, fall, and winter. This is really important to remember when you're coming here during the winter months. If you're coming during the summer, it gets really hot. Unlike the southwestern states which have dry heat, the temperatures are quite humid and uncomfortable. During the spring and fall, the weather is completely unpredictable.
