Rude?

I'm at the alterer for my second fitting (squee!), and it happened to be a busy day for them.  So I'm standing there, in my dress like you do,  while my seamstress is pinning and measuring and color coding the bustle (heads up bridal posse: it's a 5(!) point bustle),  and another, older, lady walks in the shop carrying some white undershirts. She heads directly towards my seamstress, who is on her knees, pinning and measuring and color coding my bustle to talk to her.

The older lady first apologizes to me for interrupting and attempts to smooth over some things by telling me I look beautiful (which, yes, I do, but that's not the point right now). The older lady's husband is waiting in the car for her and that's why she can't wait for her (my) seamstress to be done with my fitting. She needs the neckline changed in the undershirts she's carrying for her husband who's waiting in the car asap since he just had a something-ectomy in his throat, so the crew neckline irritates him.

Which, I get that she's on a bit of a time crunch. And I have some time so I'm not rushed at the moment. But then the older lady keeps discussing the neckline, about what she needs, and how she needs it soon, all while my seamstress is still on her knees at my hem with my gown in her hands. My seamstress has to stop what she was doing to feel the shirt, explain something, and then finally send her back to the front desk to schedule the pick up time.  Then she can get back to the bustle of my dress which takes another 15-20 minutes to figure out, uninterrupted.  

I know that my wedding is not the center of anyone else's universe except mine (somewhat dr soc's but I think we know it's overall more my thing), and she did tell me I was beautiful which is the quickest ways to break down my defenses. But it still felt a little rude to just barge into my appointment time. My seamstress was clearly working with a bride (we don't just stand around randomly in our dresses (do we? I don't)), in the middle of something. And it wasn't like there weren't other people there who could help her either, she had to have my seamstress.  While I have just as much a claim to these ladies' time as anyone else, and everything got done for me in a timely manner, it still just felt a little rude.
