I've never had a bad experience at my local counter per se, but I do wish there were more employees. There's usually 2-3 there at any given time, but being as it's the only counter in the city, it's usually pretty swamped, and quite often one of the MA's is doing someone's makeup. I also wish we had more E/S colours, as I'm fairly certain we only have about half of the colours in the permanent collection.
I have to agree with the other people here about the testers, though. I've seen girls just shove their fingers into E/S testers or even try out glosses straight from the bottle. I mean, what do they think the jars of Q-tips are for? I always use those for E/S testing, and I always ask to test lipsticks/glosses, so they can sterilize them before and after. Maybe it's just me being anal, but I sort of wish they'd post a little makeup counter etiquette sign by the testers or something ...
