Especially on early 6am flights, don't drink tomato(e) juice (or open a fresh can) while wearing a white dress shirt. Also watch out if you have a moustache, as the juice may drip from said moustache to said dress shirt. Beware of the sleeper next to you with a drink on their tray, as they jerk awake and scatter glass & contents all over.
