Kardish is a health food store, and they expect you to acquire far more knowledge than the average retail job. You're expected to provide advice that is almost on par with a dietician despite it simply being a retail service, while also receiving minimum wage.
The worst part of the job is that they put a great deal of pressure on you to drive sales. You must start conversations regardless of whether the customer is seeking it or not, and they also frown upon you if you don't turn a single item purchase in to several items. I realize that is a big part of sales, but when they have an older demographic that trusts what you say it very quickly feels like you are ripping them off. They also don't mind pushing pseudo-science information if it means someone will make a purchase.
If you have no problem constantly talking people in to things they don't want or need, then this place might not be bad for you.
