Now THIS is customer service! On Sunday, a Harris Teeter grocery store in Charlotte, North Carolina, gave away free groceries to 60 or 70 customers when a computer problem caused the cash registers to stop processing transactions properly. The store promptly closed its doors, but there were numerous customers inside when the incident occurred. Some customers had to wait in line for about 40 minutes while store employees fixed the problem. During the wait, store employees served samples of turkey and ham subs, cheese and crackers and sushi. Any lingering frustration with the wait disappeared quickly when customers were told that the store would give them the groceries in their carts for free. One customer said he received approximately $110.00 worth of free groceries.
