I sincerely believe it was just to be a jerk.

As soon as I said I had to use the restroom when she asked me about my obvious distress, she slowed down to a crawl although she'd managed to get through my spouses bag in just a couple of minutes. We both travel to Europe with small carryons. I'm neurotically organized and use the packing cubes, etc. So, she would take 30 seconds to SLOWLY unzip a small cube. I don't even wad up socks - the are all separate and flat - so, she'd take each short sock out individually and hold it up and inspect it and turn it inside out. I vividly remember my bras and panties being dumped and left out on the on the table (I got to repack my bag, IIRC). I was dreading her inspection of my pants because I figured that would take 20 minutes just for two pairs of jeans. It just wasn't very professional or efficient, IMO.

If we had been flying back from Amsterdam or something, I might have almost understood it, but since the slow down started the minute I said I had to use the bathroom, and a supervisor eventually told her to move it along already, I think it was simply a power trip. I could be wrong as perhaps needing restroom looks suspicious, but to go from a reasonable speed through my spouse's bag to unbearably slow for my bag, power play seemed a logical guess. I've never shied away from accepting my responsibility - I learned to just be neutral no matter what because it might have appeared to be a reason to be suspicious. And I now ALWAYS use the restroom before landing.
