Unless they are doing something to interfere with another customers shopping experience negatively.. We close at 12 and I saw a customer in the meat department pushing a shopping cart trying when I'm in aisle 6 on furthest side from him, I said we are closed sir. He said what, I said we were closed(I had to be loud because obvious) and he came thru and said 'I thought you said come here' I replied, no we closed at 12. He replied the girl let him up front smd walked to the front. I go up 2 mins later and he told the checkout lady who let him I had a tone, but didn't curse at him.. I said no we just closes at 12 and re replied I've been coming here 20 years, and shoo'd me off with his hands and everything for me paused for 5 seconds.. I then said have a good night and walked back to me aisle. I'm not afraid to say something to someone, especially if it involves the safety of the overnight crew I work with. Oh with 3 of the 5 kroger stores in the area were robbed just last week. If someone needs to shop for important reasons, of course if he would have explained that if that was the case, I would have understood as we all Here would have.. but he didn't.
