So last night after over indulging the munchies, I skipped breakfast and had Subway for lunch. Tis the day their damn a/c was out but they said the fridges and coolers were still good. I had the tuna sub and now I can't stop thinking maybe the hot air from the store made the tuna bad. It didn't really smell or taste funny but the top of the tuna before they scooped it looked darker in coloration like dried out. I'm thinking this is paranoia. Any sandwich artists out there or food safety buffs?
