### User's Query:
State the first name of male clients who did not receive timely response from the call center.

### Extra Knowledge:
first name refers to first; male refers to sex = 'Male'; did not receive timely response refers to Timely response? = 'No'
SELECT T1.first FROM client AS T1 INNER JOIN events AS T2 ON T1.client_id = T2.Client_ID WHERE T2.`Timely response?` = 'No' AND T1.sex = 'Male'
