Talking about chocolate chip cookies I remember there were a couple of airlines that would bake them fresh in FC. The whole cabin smelled like a realtor's open house. The good old days.....
But we were adressing the hot towels. Some airlines serve them with some sort of fragrance, sometimes quite refreshing. However, at NW we have to take little babysteps. First the towels, then the temperature, then the fragrance. Let's get surprised.
