Sub Sandwiches

We had our family Christmas today at our house. My wife's two sisters and their families were in attendance, along with my wife's parents. We decided to have the gift exchange today, but still have another dinner tomorrow. Today, we decided to do a quick lunch, which included appetizers and a sub sandwich. We've ordered large sub sandwiches before and they've always been a hit. But, it occurred to me today that this may not be such a good deal. Here's the catch. You can go into any Subway and order a 1 foot Subway club for $6, which includes all of the condiments. Not bad. We ordered a 3' sub club sandwich which cost $12 per foot. So, why didn't we just order 3 1-foot long subs? We could have spent half as much. LOL. I'm not sure of the logic there, but I'm guessing that's why Subway does such a great business. To be fair, I think the 3-foot party sub was actually about 4 feet long, and it was twice as wide as their regular subs, so in essence, I believe we did get twice as much sub, but at first glance, it still seemed odd.
