Screw Walmart. During the storms here in NC, I went there to buy some relief supplies, and it was awesome to see the whole store getting picked apart by people buying supplies to donate. What was definitely not awesome was the only 3 checkout lanes open out of the total 12, because Walmart has a 3 per employee rule and they don't want to assign enough workers for the checkout lanes, even during times of crisis like this.
Only 3 self checkout lanes should be open per employee. If you have a self checkout area with 12 terminals, there have to be 4 employees to keep them all open.
