KUALA LUMPUR, June 6 — Pizza Hut Malaysia said it is looking into a customer's allegation that one of its outlets had barred her and other non-Muslims from dining in until 8.30pm.

The chain was prompted on Twitter to examine the claim made by a user who has since made her account private.

In the initial tweet, the woman wrote that she was told upon entering the Pizza Hut outlet at an unnamed location that non-Muslims may not eat there until the appointed time.

“Thank you for informing us. We are in the midst of investigating this matter now and we definitely do not take this lightly,” Pizza Hut Malaysia replied on Twitter.

Muslims are currently fasting for their holy month of Ramadan.

Malaysia has laws that punish Muslims who fail to fast without reason as well as eateries that serve Muslims during fasting hours.
