I'm glad that MA's don't mind lists, I usually take one for myself to remember to look at things, but I am too sheepish to hand it to someone to pull them for me. To me, it would seem like "Here's the stuff I want, now go fetch it." lol. I'm glad you girls don't feel that way.
I'm not a MA, but I think the perfect customer is the HONEST customer, and vice versa. I don't want to be talked into buying something I don't need, and if I, the customer, am asking your opinion, I really do want your *honest* advice. Yes, you can word it nicely, such as "That's maybe not the best color on you. Let's try something else," but please don't try to sell me something that I will want to return the next week because I didn't really love it in the first place. And as the customer, don't lead a MA on to think that you're going to buy this and this and this. If you're just browsing, TELL THEM. Don't waste their time and have them try a bunch of stuff on you if you have no intention of buying. I think the only thing I've ever asked a MA to do for me when I was just poking around was to sanitize a lipstick for me to try on. The MA's time is money, and I've seen them do girls' makeup, only to have them hop out of the chair and just say "I'll think about it."
