SAN DIEGO -- The day before Thanksgiving usually means big business for supermarkets around San Diego. But for the three supermarket chains wrapped up in the grocery dispute, business has been a lot different this year.

The scanners continue to hum at the Keil's Supermarket in Clairemont. Brian Haire runs Keil's Supermarket.

"We work really long hours -- dark to dark. I haven't seen my sunglasses. I don't know where they are," Haire told 10News.

Haire said everyone at the store has been working overtime to keep up with demand.

Shopper Jane Harris said, "I was telling (that) lady that we need traffic lights at the intersections today."

Customers are also trying to keep up with the demand.

"Crazy is not the word -- it's worse than crazy," said Lewis Ford, another shopper who does not want to cross the picket lines. "I think without question that people would rather not cross picket lines. Keil's, or someplace like this, is the way to go."

The added business at Keil's is not about to be turned away, 10News reported.

Since the strike began, the sales of swiss dairy products have tripled. However, down the street at Albertsons, business is down. There are plenty of parking spots and according to one shopper, there is no wait at the checkout counters.

"It wasn't very crowded. There's a good amount (of food). It is easy to find things," said the shopper.
