A university in England has banned a Mexican restaurant from distributing sombreros as a promotional gift to students.

University of East Anglia’s student union said the hats, typically associated with the Mexican culture, were “racist” and violated a school policy that prevents vendors at a local fair from distributing “discriminatory or stereotypical imagery,” according to the Guardian. Employees from Pedro’s Tex Mex Cantina insist the gift was meant to celebrate Mexican culture, not demean it.

“As we handed out the sombreros we were told it was ‘culturally indifferent’, which we think is a shame because we are not doing anything to offend and we are just celebrating the culture,” said Pedro’s general manager, Matthew Ward, the Guardian reports.
