Thank you all for your empathy and thoughtful replies.
Anne-Marie---LOL the airport-hand lotion gig sounds pretty good!!
Malka--I like the secret shopper idea!

What transpired today at the restaurant was Mr. Boss pulled me and a co-worker aside wanting to know what our future intentions were with the restaurant. Were we moving on, or sticking around for a few more years?( almost everyone at the restaurant is a long-term employee) They had plans, and wanted to know who the could rely on. So of course, with the subject being broached I jumped in with "What are your intentions regarding me?" Mr. Boss got indignent that I should even have to ask, and I described what I thought was going on. He called Mrs. Boss over and we had a sit down and I expressed how I felt, and that yes, I was looking at other restaurants since I was only working 2 shifts. I feel as though we worked some things out and I can expect more shifts, they will work around my doctor appointments and are going to let the new girl go. I feel much better now after the airing out session, and Mrs. Boss realizes I know she was discouraging extra hours for me--she has changed her tune.
