That is "extreme" for this person to do this a 2nd time because of a vendetta against Kroger. Another thing to watch out if you work on the front end. Disgruntled ex-employees coming in to destroy the store!
Many stores have the security poles in front of there stores. Target is one local here that does. Kroger should think about installing these to protect the customers,employees and their stores.
If she worked at Kroger and didn't have a "beef" with managers on power trips, Key Retailing, e-schedules, or something else like that, maybe she was upset about "organic cage-free" chickens (See separate thread from today). LOL
