The women were on their way from Brooklyn to Manhattan on Saturday when they exchanged what they call a "peck" on the lips.
The couple, who say they had been drinking but weren't drunk, recorded a cellphone video showing the driver, 35-year-old Ahmed Elbotari, booting them from his auto. "I did what I believe is my freedom", he said.
The couple questioned him about his decision and asked him why they were not allowed to kiss. As they were crossing the Manhattan bridge, Iovine said the couple leaned over to share a quick kiss. "She thought he was joking".
Iovine refuted El Boutari's recollection of the incident, telling the Daily News that "we would never disrespect someone else's vehicle in such manner and we always handle ourselves appropriately in public".
"It's disrespectful", El Boutari says.
Alex Iovine, 26, and her girlfriend Emma Pichl, 24, say they were headed from one birthday party to another in New York City when they requested the ride-hailing service.
"I don't give a shit about them".
During the altercation, when Pichl started recording the scene, "he grabbed Emma's arm to try to get her to stop", Iovine said.
"I think we are going to steer clear of Uber for a bit", Pichl said.
A same-sex couple claim they were kicked out of an Uber by its driver because they were kissing.
Elbotari also spoke to the News, claiming that the couple was simply acting obnoxious, with one of them forcing the other to smell her armpit, playing music loudly on their phones, putting feet on the seat.
The couple filmed the altercation on a mobile phone and posted it on YouTube.
"It's my own vehicle".
She said they were in lower Manhattan when the driver pulled over, opened a rear door and ordered them to "get out of my auto".
Tough experience yesterday. Help spread the word about this Uber driver. It's OK to chat with other people in the vehicle.
In video posted to Iovine's Facebook page, you hear the women asking the driver, "What's the issue?" And don't touch or flirt with other people in the vehicle.
Uber has behaviour rules amounting to, basically, no sex in cars. It's common courtesy not to shout, swear or slam the auto door. "You can't do this in the auto". Please respect those differences. "They reportedly have been refunded the cost of the $22 ride".
An Uber spokeswoman told ABC News that they are in touch with the women and investigating the incident.
"Uber does not tolerate any form of discrimination, and we have reached out to the rider regarding her experience", an Uber spokesperson told Newsweek in a statement.
