Every once in awhile BOS has this witch working the security area stopping people whose rollerboards don't fit into the little example overhead bin. It's extremely stupid as many bags don't fit into the example yet get into the overheads just fine. I've seen her send back unknowing folks to have their bags checked. I can't wait for the day she stops me and I tell her I fly 100k miles a year and have never had trouble getting my bag in the overhead (wheels first mind you).
