Church on Sunday mornings, SIN on Sunday evenings? Actually, it's not what you think.
Rather, it's a sign aimed at gathering service industry workers together for camaraderie. SIN=Service INdustry, get it? Or, Service Industry Night. (Or, Self-Inflicted Nonsense, my favorite of the 30 SINs listed on the Acronym Finder.)
Just the folks at George's Tavern on North Main having a little fun. David Popoff, George's genial host, insists, "I applaud the service workers of America." At least, we think the picture came from David. The sign is over his front door.
