That's what Trader Joe's does. They actually have bells at the cashier stations. If a cashier notices the lines are getting too long, they ring a bell. Then other employees drop what they're doing and come over and open unused cash registers.
I love TJ's.
Wish there was a Trader Joe’s closer to us. I really think they offer a quality product at a fair price.
I’ll be relocating to the Houston area before too long (I hope) so I was glad to see TJ’s is expanding to TX.
