Checkers should teach their employees how to treat their customers!

So my mother was wrongfully accused of theft at Checkers, Southgate a few days ago. Thank God for the CCTV footage which proved her Innocence. Those employees at Checkers, the manager included, didn't even have the decency to apologise appropriately after wrongly accusing her of theft, humiliating her, embarrassing her & threatening her too. I'm really disappointed with the staff of Checkers. I expected better from them. Checkers should teach their employees how to treat the customers.
