It may sound cliche, but it's definitely the people.
Not be so demanding, more patient and more thorough training.
Interviews are always stressful, and I'm glad when they are over.
Maybe a little more relaxed, but if people were trained properly, it would run more efficiently.
It's hard work but the pay is too low. At least an extra $1-2 per hour would be more fair.
As before, more training is needed. And they need to stop gossiping so much and help each other out instead.
