Funny thing. While in the ticketing office, the young lady asked me for the ticket receipt (seems they have no way to recall the record of the transaction). I forwarded the copy they sent me by email to her while sitting in front of her and even confirmed with her that she received it. "Yes po" was her answer. Yesterday, I received an email request to please resend the receipt! Such efficiency should never go unpunished! 😠 😠 😠
