i didnt know until that day

went tour-hunting with parents on sunday, amazed to see the scale of how big a particular tour company is.

electronic screens to show queue number

wat???

thats not all, they even have different sections for different tours.
ie different queue nos for different tours.

yikes...

it looks as though u're waiting for your turn to see the doc at the polyclinic.

then there's the semi professional ones, they give u a slip of paper showing your queue no, n call out your queue no manually.
