I was in the CVS Pharmacy(former Longs Drugs) in Concord, California near the Concord Bart station and I saw that the signs were all in English and Spanish. This is the first time that I had seen a CVS store with bilingual signs. The Spanish was in smaller letters under the English letters. They did this for the department signs as well as the gray aisle signs. I also noticed that the Pharmacy signs were the cardboard type instead of large letters glued to the wall.
I don't know if they already used bilingual signs for older CVS stores in Los Angeles/Southern California, but I assume they put in bilingual signs since Concord has a high number of Spanish speaking people.
Also this store has a large open hole in the wall that leads to the stockroom. You can see inside of their stockroom and see the old Longs decor and floor. They did not bother to remodel inside of the stockroom.
