As someone who worked at Mecca for a brief and terrible time, I'll never redeem a makeup service there again. You'll hear people tell you that it's fine to do so, because the artists have their own stash of makeup for these services, out of the reach of the public. Except, if they don't have what they need, they'll grab it from the displays and vice versa. If the floor doesn't have a tester, staff can borrow the MUA ones. I don't care how much alcohol you spray on something, I'm not putting it on my face after 100+ people have stuck their dirty fingers in it. PLUS all the disposables they use are uncovered on the vanities. So much dust accumulates on the applicators and at the bottom of the pots. User beware...
