Re: $3000/mo cruising budget
Hot dogs, sausage, wursts, are a wide concept. Very wide price range depending on what is in them on how many health recalls the source has had.
Eating out because you can't cook at home is also not what it might seem. In many places, including India, people can't afford to buy FUEL for their primitive cookers, it isn't like the urban Old World or New where all you do is turn the knob and pay by the unit.
Ditto for yacht clubs. In the US many of them have a restaurant as a split convenience or accommodation, and the members are required to spend xx dollars per month in the restaurant, in order to help ensure it makes enough money to keep it running. Others charge stiff rates to keep out the riffraff, while a few actually just run it along with the bar as a convenience to the members, at a reasonable price.
So what is "expensive" depends a great deal on where you are and local circumstances. I'm told that in ancient Rome, plain citizens weren't allowed to cook at home--weren't allowed to, even if they could afford to. And that when "Nero fiddled while Rome burned' it may very well have been traced back to a cooking fire. We'd save a lot of lives and property in the US by banning domestic "flame" cooking devices, too. (G)
