I was just here yesterday morning and I was served by two rude employees at the Distillery District store (both young women) who called me fat and talked rudely about me to each other right in my face for ordering a cinnamon bun at 11 am. One said "What's wrong with people who order cinnamon bun before noon? They're going to get fat." The other girl just laughed and agreed.
This is very hurtful and may be triggering for those who may have eating disorders or anyone else with body issues. By allowing this behaviour to slide, you are encouraging bullying and harassment of customers. I hope you can get your team to reconsider how you treat your customers.
