Ann Siner says there's no formal appeal process. At the very least, she hopes she can get one created so other business owners can have their say.
The ad in question is for her men's store, Well Suited.
It reads "Make a Booty Call," and features a picture of a boot.
Valley metro's CEO called the ad "sexually explicit to most everyone."
Two other ads for consignment shops, one which read "buy a bigger chest" and showed a picture of a furniture chest and one that read "wanted: one night stand," showed a picture of a nightstand, were originally rejected, but were later accepted.
The only one that was accepted by Valley Metro read "Sell your Sole," and featured a picture of a shoe.
Siner says all of the ads were approved by the city of Phoenix in March, but were banned by Valley Metro after the trains were wrapped.
"The whole procedural to do with the ads being denied was completely unclear. The ads were on the light rail it was running a couple of days, then it was pulled. We weren't even notified for almost a two week time period," said Siner.
The Valley Metro board meets on May 21.
Siner has an alternative ad that she will present at the meeting.
It reads: "Get tied up," and shows a picture of a man's tie.
Siner says the ad campaign would have generated an additional $60,000 in advertising revenue for the city of Phoenix.
The ads have been running in Phoenix and San Diego for years.
