In my small experience, it depends on what type of tile you are using. Ceramic tyle may not have the glazing all the way down the edges of the tile. If not, it might look odd just lapping it over the vertical edge. Check with your tile supplier, there may be a matching or even contrasting edge piece or bull nose tile that can be used at the edge. Contrasting color might be good as a warning the the level changes here.
If the sides of the tile are glazed, then I'd do it like Allen suggested and it would look very nice. Just check the tile that your customer has picked out to know the best way to go. Jim.
