Market Basket workers staged a massive rally Tuesday in support of ousted CEO Arthur T. Demoulas.

But some boycotting customers voiced the same message - that Arthur T. Demoulas is their leader, too.

"Don't tread on us! We're the customers," said Norman Seibert. "It's really a boycott, now."

"In Haverhill, there are three Market Baskets - only Market Baskets - and they service a very marginal community in great part," said Inez Seele, holding a sign reading "Can't fire me, I'm a customer."
