I don't know if it's b/c you're a woman (I hate to play the gender card, but man, it's used often!), but I find that retailers and sellers in general often give women less respect. And I can't tell how many ladies of color are out there on this forum, but people of color get it all the time too, man or woman.
You know what though? I used to be the type to scream and yell, but now I just quietly demand and hold my ground. Once they realize you're not going away, that you WILL be that thorn in their side before they change their tune, they usually acquiesce. STAND YOUR GROUND. To me, success is reserved for those who are persistent.
