Czech inspectors have found that more than half the restaurants they checked up on discriminated against foreign clients. The inspectors from the Czech Commercial Inspectorate found that eight out of 13 restaurants they checked up on added extra charges to the bills of foreign customers compared with Czechs. Agents went undercover for the inspections by pretending they could only speak English. Other shortcomings were found at nine out of the 13 restaurants. The inspectorate pointed out that Prague is highly reliant on tourists with the aim that they should be treated fairly and not exploited. The inspectorate said it would continue checks throughout the tourist season and beyond because restaurants also served ex-pats living in Prague.
