That "one week in primary" bit makes me crazy, too. If you work in a craft supply store, you need to have more than an elementary understanding of the craft. Period. The end. Put your pencils down. Close your books. Go home.
The expired yeast also is virtually inexcusable. If it were expired by a few days, well, okay. However, they should check yeast inventories at least once per week and remove anything expired (or, at least, put it in some "expired yeast" bin and let the brewer take his chances). In any case, take that stuff back.
I cannot get too wound up about the burner, though. I don't expect an LHBS to be in the business of selling burners and other equipment that is both low volume in an LHBS and available other places. Oh, sure, they'll carry the stuff, but only because some customers expect them to, but those same customers should expect to pay a premium. Low volume means high price, as low volume also means high cost to the LHBS. For example, my LHBS carries 5 lb. CO2 tanks at $110. That's far, far more than I pay at the welding supply store. However, the welding supply store is in the business of selling those tanks, and my LHBS is not.
