I was discussing this with Hello Kitty just before and we both agree that there should really be a staff picks sub suggestion.
As in, video stores have 'staff picks' for good movies they want to suggest to their customers; so why can't subway do the same?
I'm not talking about creating whole new subs (i'm sure there are some rules about that even though they are franchise), but rather a 'sub of the week' with suggestions by staff of the best bread/cheese/extra toppings or filling to include.
Subway itself is made of combinations and individual creativeness, so why not let the pro's suggest one of their own?
I mean, it could even work out in their favor by suggesting extra toppings that they can charge more for. Its a way of suggestive selling.
