I am not a number, I am a free man!

I had stuff to post - parcels to dispatch - and less than 15 minutes of my lunch hour to do it in.
' No problem', I thought. 'I'll just stride straight into the post office wth a decisive look on my face and....." Oh. A moment after I strolled in, number 140 was called to the counter. So the Counter Services ticket that announced with such cruel concision that '28 customers in front of you' wasn't just having me on after all....
Result: parcels still in me bag :(
Every so often I hear people muttering about something called 'Crzzmzz'. Do you think that might have had something to do with the the unexpected post office hordes, Blipfoto?
