Awful service by the manager @BritsMall

Tell me why Checkers employees would give exceptional customer service if their managers lacks that. I had an awful experience at Checkers Brits Mall. Long story short, the item I was purchasing had a different price at paying till point compared to price displayed. Fast forward the manager was called. Ridiculous attitude, bad manners, unprofessional, he behaves like he runs a ****a shop. I will not name him here but I got his name. He told me I'm complaining about the little difference amount displayed, I told him to give it to me since it was nothing to him and he just left. How is it my fault that they didn't put out the correct price tags on their goods. I left as I couldn't handle the sickening situation moving forward. The manager need severe customer service lessons, a whole manager of such a huge company "its ridiculous"
