One, when going out to a nice restaurant to eat, don't douse yourself in cologne or perfume. The people at the table next to you can smell you, and that likely means they're can't really taste their food.

Second, when waiting at the airport, don't plop yourself down on those waiting area rows of seats. They're connected and it's likely that you just jerked the poor guy down from you forward, or, even worse, awake.
