Mine scrapped the bottom for me as well "You need to do better answering call boxes" to which I responded "If a call box goes off, I'm the first to respond. If I can't get it and know someone who should be in the area I'll ask if they can get it. And worst case scenario, at the 15 seconds mark, I'll run to grab it." That's especially hard in a 2-floor store. They said I needed to do more. Claimed I didn't backup enough "Ask any of the GSes, I back up before they even think about asking." There's a reason about half of the GTCs I get come from backing up.
Finally an ETL told me I need to be more FFF. I asked if she could cite a time when I wasn't. She couldn't, but concluded "It's impossible to be FFF all the time, so there has to be a time when you weren't." Somewhat ironically, after that review, I was the most pissed off I'd ever been on the SF, but I had a trainee scheduled, and I did a fine job training her and showing the ropes while being, you guessed it, FFF.
