RM10 Zeti ZC Replacement and A nice number too

I bought 'sayap ayam panggang' at a nearby stall for dinner and paid RM50 for a RM10 food. But to my surprise I received two RM10 notes in the change that are most welcome to us numismatic lover.

First is a replacement ZC prefix:

Second is a nice number LT4008888:

Although the condition is of course circulated but I am somehow grateful. Any of you have your interesting story of where you found your replacement or valuable notes?

Thank you mas.

Cheers to all.
