OK.
By now you've got the gist : Boat Sauce is amazing, you'll use it on everything, etc. But here's the deal : It is, and you will. And now, you have reached this point where 4 bottles just aren't enough, because you like to keep a bottle at the office as well as home-maybe one of each-and then you need a backup. So 5 bottles totally makes sense. Truthfully, you're being quite pragmatic here, and maybe a tad conservative.
