Why not cake for one? Does no one want to buy single

Why not cake for one? Does no one want to buy single slices of layer cake? Or does “Cake for One” sound lonely and desperate, and QFC would rather make single customers eat their first piece of cake with the second piece set before them, a reminder of the dessert-lover who is not there? Actually, does anyone actually buy cake for two, or do they buy it for themselves and down the second slice guiltily? Is “Cake for Two” just an easy way to get rid of the whole cakes that don’t sell? Does anyone buy cake for two before midnight and the consumption of any number of inhibition-reducing substances? Do any of the QFC cakes for two stand out as being particularly tasty? Just curious.
