Making toast in a traditional way is flawed, and has been for generations. In your average toast-making session, you can be confident that the vast majority of people are going to be using a toaster. You'll always have those oldschoolers that will use conventional methods (such as a grill), but for the purpose of this, those select few are excluded.
This flaw also relies on the fact that, given most circumstances, people are most likey to be doing more than one slice, either two (or more) for themselves, or kindly toasting a slice or two for a friend, loved one or relative.
By design, nearly every toaster ever made can accomodate at least two slices of bread, and such a design is by far the most popular, albeit four and six slice toaster are coming into fashion. Bread is placed in the toaster and then the lever is pressed down. The toaster then heats the bread (or performs a lower-heated defrost cycle first if the bread happens to be frozen and your toaster supports that function). The toaster toasts the bread to your preference, as set by the dial or buttons found on all toasters, and when finished, will cease toasting and then pop up your bread, filling your kitchen with that "just toasted" smell.
Though here lies a flaw. It is almost inevitable that all toast is going to be spread with butter (or margerine, or, god forbid, lard), all of which have a melting point lower than that of toast fresh from a toaster. Though as you're probably aware, toast is not a good insulator, and it's effectiveness at retaining heat could only be described as mediocre at best.
Thus, while with your first slice you'll butter, the butter will melt thoroughly into the toast, giving it that ever so tantalizing taste, the second slice (and consequent slices) will only be a half-melted mess. The butter will not melt evenly and thorouhly as it did on the primary slice, and when you go to spread any extra thing onto the toast (jam, chocolate spread, marmalade and peanut butter are popular choices to name a few) it will mix with the "raw" peices of butter still there and create a taste experience that'll never be as nice as the first slice. (This is why, statistically, most people will keep the first slice for themselves, and prefer to share only subsequent slices with others.)
The easiest and most effort free solution to this problem is to modify the toaster's in-built timing mechanism (and possibly the push-up mechanism, as most toasters will push up a whole row) so that toast is released sequentially, with enough time alotted in between each slice being ejected for the end-user to butter and spread each slice, giving each slice that "First Slice Taste™"
