Albertsons / Supervalu Age discrimination? Meridian, Idaho

Has anyone noticed age discrimination at Albertsons' / Supervalu? I was hired at Albertsons then as soon as I filled out my new employee paperwork, which is where they first learned my age, I wasn't given any hours. As soon as I successfully completed my required training the store director called me in an said he decided to "go in another direction". Huh? I hadn't even had a chance to work IN the store yet. I was mystified. That is when I realized that during training, the trainer started to treat me harshly and started bullying me, as soon as she found out my real age during one of the scenarios. I looked at the employees at the store and there certainly were some older ones there. I'm thinking the store director has decided he has had enough older employees and now wants younger ones. The other new hire, who was hired on the same day as I was, was treated nicely and was given hours even before she started training. Granted I look younger for my age, but why the sudden change of attitude when they realized I was over 50?
