Judging by the fuel prices, you'd think the Mobil station across from the Boca Teeca Country Club offers petrol Cordon Bleu instead of plain old gasoline. And while what you get at the pump is the same old, same old, the convenience store shames most gourmet boutiques. Clear-plastic bins of loose jelly beans and other candies cover half of the front wall -- you can fill a little plastic bag with cotton candy, caramel popcorn, bubble gum, and pear-flavor Jelly Belly beans. Next to the candytopia stands the self-serve frozen yogurt station; faced with eight flavors, three sizes, and several toppings, one can easily fill up with more lactose than octane at this Mobil. The station also offers cold drinks, a few plebian items (for example, potato chips), and a glass case of croissants and glorified donuts. Ain't Boca grand?
