The quality and knowledgeably at Michael's seems to be hit or miss from what I've experienced. Some of them really know their stuff. Others don't. If I don't like them, then that store doesn't get my business.
As for their handling of items, when I had my Spike's poems framed, I told them that I wouldn't leave them. Plain and simple.

(The one guy was a Buffy fan, so he understood.) They had no problem with it and actually encouraged it. They told me that it's the wait for the materials that takes the longest, but when they did come in, it would take a day to frame and finish. I dropped the poems off in the morning, and picked the final product up that night.
Long story short, if you don't want to drop the item off, don't. If they put up a fuss, it's B.S. It shouldn't take more than a day to get done. No need to leave it there for 2 weeks +, just to sit and wait for materials.
