Wellll,
sometimes its true.
Before I worked in the industry I would only shop at the Nordies MAC counter because at the time, they were the nicest.
Now, I know the girls at both counters but I can only shop at the MAC store since I have a card. But I will say this - people change when they move to MAC - I have seen it, witnessed it, and for some reason they think they are all that and a bag of chips when they first get to MAC, like its the end all be all of jobs.
I had one friend who noone talks to anymore, she is so stuck up now and another who just works at the MAC store just for a job - doesnt care about makeup any longer and cant wait to get outta there. Retail sucks for some people, customers change you, when you get dumped on so long it happens. And another who just loves it to death and who will probably die there she just loves it so much and you can tell, she is so nice and happy. And tons of others who literally strut around the mall like they own - just because they work at MAC = please. You dont make 200,000 a year, you are not the next top model, you didnt win the nobel peace prize, - you sell make up plain and simple and it might be hot makeup but its still makeup so calm down, relax and please can I get some service? I've been waiting in line for 15 minutes now!
So, I can totally relate where some MAC counters are really mean and rude, but then so a lot of other makeup counters, and some are really really nice.
