I believe everybody deserves a break. Standing on your feet all day without a break is ridiculous and so what if everybody goes to break at the same time if they post it up when they close for break then you should know when not to come.
If they tell you a time when to come pick it up I understand being upset but maybe they hit bad traffic or something happened they could make get back on time.
That is usually why I just wait till thirty minutes to an hour before showing up and do some shopping while they are closed. Personally I love Walmart not every store is perfect.
