I dont know how much they pay in the Bay, but I work at the Trader Joes in Kirkland, near Seattle and they started me at $9.50. I make a lot more now but I had to earn all my raises. Your up for raises every 4 months. Depending on your manager, if you earn it, you could be making 2 bucks more in a year.
I like the job its hella laid back. Its almost like working at a mom and pop grocery store. The only thing that pisses me off is the customers, some are cool but some are way to pampered and expect to be treated like that.
If you have anymore questions ask.
