she could have been a freelancer, we have had 4 freelancers in the past 2 weeks because we are shrtstaffed and freelancers dont get 'real" mac training. so there were several times one would have to ask one of us to help her find something like a product or brush. also sometimes its hard to remember every single thing, im a very visual person, im bad at remembering names, so yeah i may stare blankly when someone ask me about a lipstick from 2 yrs ago, it doesnt mean i dont know what im doing, if you showed it to me though i would say "oh yeah, it was limited". our old trainer was bad at remembering brush numbers too, she would call them by large shader, small shader, angled brush because she would always forget the numbers. some people especially mac artist are very visual, so names and numbers get lost in confusion and thats why we may ask you to "show us". keep in mind everyone is different in how the remember and recogonize.
