ALBUQUERQUE, N.M. — A same-sex couple from Portland, Ore., said they received an unfriendly welcome when they arrived in Albuquerque, N.M., recently – they claim they were forced to sit in back of the airport shuttle bus because they were holding hands.

The couple, Ron McCoy and Chris Bowers, said the incident happened on June 28, but that they still haven’t received a formal apology from the shuttle bus company and they are considering legal action, reported KRQE-TV.

“I saw him look at us, look down at his hands and he looked so angry,” McCoy said. “He just blurted out at me, he goes, “Okay, if you’re going to do that, you’re going to the back of the bus.”

Shocked and not wanting to cause problems, the couple obeyed.

Watch a report from KRQE-TV:

KRQE reports that a manager for the shuttle operator said the driver’s actions were inappropriate, but that he did not consider it discrimination.

The couple said say they filed a complaint with the American Civil Liberties Union.
