Air for now... I am in a sterile environment atm.  
Yesterday, I felt like getting a big hefty, old school hoagie and not some overpriced fancy mini sandwiches at the french bakery I go to.  There is a subway (sandwich shop) near there so I went to get a foot long.  $8? I kept thinking of the $5 foot long commercial and singing, $8 foot long.  Guy asked me "double meat?"  I said sure.  How is it double meat if they still put a single layer of meat and cheese down?  Then my "$5 foot long" was $8 after tax.  
Now I remember why I haven't been to a subway "restaurant" in 6+ years.  Nothing has changed.   Well... they did toast my sandwich now, which made it taste stale instead of toasted like quiznos.   I miss the days of working near this great italian shop.  They would grab this fresh crusty italian bread and make me a sandwich with quality cold cuts and extra virgin olive oil and balsalmic.  Stacked so high I couldn't get my big mouth around it.  Getting hungry...
