I did have a friend who I stopped talking to as got fed up with her racist comments. She was a colleague who retired 3-4 years after I started. Where I work we have/had colleagues of different races and have no issues talking to them. She was saying racist comments and false things about them which upset me.
I was on a day out with her in a town where need two buses each way to get there. She said another racist comment which I snapped and said something on the lines of I am fed up hearing your racist comments and going home.
I felt very bad doing this as she didn't know which buses to catch for the least amount of time traveling - one was more direct and two others went around the various estates. Was very surprised that her DH or she didn't ring me later that day or day after having a go at me.
Forward 4-6 weeks and it was a retirement do for another colleague. Heard that she was going to it (the cheek) and don't remember her talking to the retiree at all which is insulting imo.
The pub which we go to has an area which is used for events as can have the tables set as you please and an area between the tables where you can stand and have a chat with others.
She never spoke to me then shouted somethings which are untrue. There was silence. The DH of retiree and a few past and present colleagues asked her to leave. The sad thing no one can remember anything of the do apart from her and her tirade of lies. Plus about 8 months later the DH of the retiree died as diagnosed with a very aggressive cancer and was too late to do surgery.
I have no idea why my former friend who was a lovely, caring understanding friend became a racist and enjoyed saying bad things about everyone.
Her behaviour that day cut off the ties of other colleagues (past, present and now don't work). About 2 years after the incident, I was driving in a supermarket car park, about 2 miles from where we live (live about two thirds of a mile apart) and saw her and DH's car. I decided to go to another supermarket of the same chain 1.5 miles away just in case she bumped into me and wants a go.
