There will be the inevitable visit to the "facilities" This cannot be avoided and should be planned for. It has been said that you can tell a lot about a dining establishment by the condition of its bathrooms. How do you imagine the kitchen to be if the restroom looks like a Detroit Greyhound station bathroom? Toilet paper? Get the good stuff. Soap? Antibacterial in an attractive container. Air freshener?...Umm absolutely especially if I'm coming over. Hand towels? keep them handy and change them often. Get rid of the magazines in order to avoid traffic jams because you invited the guy that really does read Playboy for the articles.
