Yeah, Subway has an odd, repellent stale onion bread/cardboard aroma which assassinates any appetite I walked in with, to the point I have to leave the store.

I worked part-time at subway many years ago. The stench was worse than the stupidly low hourly rate. My work clothes had to be washed separately from other clothes because they could taint a whole load of washing with a faint but distinct whiff of Subway 😒
