This morning one irritating incident

Long queue buy hawker food
When sinkies food is fully packed and ready to pay. Hawker waiting for his cash, everyone waiting for him to move

He suddenly pull out his handphone and activate his paynow. 
Scan the barcode
Key in his password
Key in the amount
Both wait for it to pass through

Why can't irritating sinkies get his paynow ready, why must last minute then activate

How u know it is a Singaporean? It might be  PR pretend to be Singaporean
