Officers have condemned two shoppers who brawled over a “10p sandwich” at Asda in Broadheath.
Customers watched on in amazement as the fight broke out just before closing time on Sunday evening.
One man suffered minor injuries in the incident but no arrests were made.
Writing on their Facebook page, officers from GMP Trafford South wrote: “Waste of police time award goes to several patrons at a local supermarket.
“Instead of acting civilly when purchasing discounted ‘whoopsies’, they decide to scrap it out.
“This causes some much unnecessary distress to other law-abiding staff and customers, resulting in several urgent calls to the police.
“Ultimately, this is a complete waste of police time and public funds.
“If you choose to treat yourself to a cheap discounted bargain, please be respectful in doing so.
“Certainly don’t fight over a 10p sandwich when trying to save some dough.”
Anyone with information are asked to call police on 101, quoting incident number 1474 of February 4.
Information can also be passed to Crimestoppers, anonymously, on 0800 555 111.
