I can't believe I had to wait in line for 30 minutes to pick up an item at Best Buy that was supposedly ready yesterday. After 10 minutes my son had a meltdown from the sensory overload of spending so much time in the bright, loud store.
You could see employees standing around doing nothing while I waited in line. When the manager working the desk made a comment that 'someone was a little cranky' (instead of apologizing for the inappropriate wait), I almost lost it. I'm still pretty angry but at least I got a $50 gift card after I complained to corporate, Playing the A Card.
