A Walmart customer called 911 after a self-checkout glitch resulted in an inflated bill. The incident, shared by an employee on Reddit, began with pricing errors on the self-checkout register. The customer mistakenly rang up 999 avocados instead of nine, causing his total to exceed $1300. Despite attempts to rectify the error, the customer became irate and demanded compensation for distress. Walmart's self-checkouts have been in the spotlight for incorporating new security measures. The company has been investing in store renovations but has not disclosed if self-checkout changes are part of the plan. Walmart has yet to comment on the incident. (Dailymail)
