An elementary school in Oregon has done away with a policy that allowed pupils to pay to go to the potty.

Children at Cascades Elementary in Lebanon, Ore., were given school “bucks” that they could redeem when they wanted to go to the bathroom outside of their scheduled breaks, according to ABC News’ Portland affiliate KATU. But students were opting to hold their water so they could hold on to their fake money to buy items at the school store, the TV station reported.

Parents complained that the school was punishing kids for needing to use the restroom and causing undue strain on their tiny bladders.

One parent told the TV station that her first-grader had an accident at school while trying not to go to the bathroom.

“I just feel my children should not be punished for having to use the bathroom, even if they didn’t take advantage of a recess break because they may not have been thinking of it. They’re children,” she told KATU.

The school’s principal ended the policy, however, she told KATU it had been helpful in keeping students from overusing bathroom breaks to get out of class.
