Never even heard of hummingbirds being so trusting!! You must be special!
We used to live in the mountains near Yosemite. We had a single plastic flowered hummingbird feeder. When ever it got low the birds would fly around my husband, almost hitting him. Once I witnessed this when he was headed out to the barn and he just turned around and took down the feeder and refilled it. He said, "When they start doing that I can't get anything done until I take care of them!"
They were a lot more fun than the bear that tried to get to it. DH raised the feed higher into a tree after that!
