Ice---Costco is supposed to be a good employer, why not lay this on the dept head? Cinderblocks are cement--but might be too pourous for meat dept. But, a brick is exactly 2 inches high. Sanitation is a real issue--that is one reason that I only buy meat from Costco. Their meat is great and they have organic chicken and hamburger---they are actually a fantastic store, but I can also see that a transfer from the meat dept would help your aching back. At least in the warehouse or bakery, you would move around more. I want to drive a forklift!! Secret ambition--too many years of being an artist and lugging heavy boxes to art shows!!
