We have a farewell at work tomorrow, so I had to pop to the shops after work. (I normally hate going when I am rushed). This was the state of the queue - motionless! I got to the till at 15 to 6, they were closing at 6. There were about 10 people in front of me, but only 2 tills open. I was eventually served at 6:30. Unfortunately it was either wait or be back there before work tomorrow.
Now, a bonus picture. I am not sure about other countries, but here in South Africa at the end of the school day all children put their chairs up on their desks, this is in order to make it easier for the cleaners to sweep. Being at the shops 30 minutes after closing time, I was tickled pink to see they do it at the shops too!
