Mind the Backstage
I popped into a Subway sandwich shop on my way home and noticed this sign as I waited in line for my order. I don’t think they’ve ever actually suggested soup to me, but I’m pretty sure this is supposed to be backstage communication (yummy pictures of soup are on the other side). The design of Subway restaurants makes it tough to separate frontstage from backstage. Quiznos does a better job I think.
