They're supposed to be in Cabo San Lucas doing mission work for the church, but doing the work that's required of them could prove to be too much for some of the girls on Preachers' Daughters.

Meet The Season 3 Cast Of 'Preachers' Daughters'

In a new clip from the second episode of the season, it appears that Cierra Vaughn has the biggest problem with her surroundings when she, Nikki, Megan and Kayla prepare meals for some of the poor in the area-especially when she realizes that the kitchen is not up to usual standards of cleanliness because it is partially outdoors.

The girls are serving hamburguesas, or hamburgers, and watermelon to those at the mission-something that the other girls seem to be coping with well enough, even if it is outside of their normal comfort zone. However, after spotting both a gecko and a bug on the walls of the makeshift kitchen, Cierra begins freaking out-causing problems with her other workers.

"This kitchen is a mess," Cierra says in the clip. "I can not productively work somewhere that's disgusting."

She later goes on to admit that it's hard to believe that modern comforts aren't available to everyone.

"I just cannot believe that there are people out here that live this way," she says.

However, her constant outbursts start grating on the nerves of her fellow workers.

"I don't think Cierra has the right attitude to do mission work," Kayla says. "You know, yelling, and going crazy. I think it's pretty clear that she has a lot of personal issues to work on."

Megan in particular seems to wonder why Cierra is there, if she's going to be so particular about her working conditions.

"She's like, freaking out, which makes me wonder why she's really here," she says.

The situation apparently then becomes too much for Cierra-and she leaves the other girls behind and storms out.

Preachers' Daughters airs Fridays at 10 p.m. on Lifetime.
