I went to the bank on Thursday. It's been redecorated and the previous system of 'who is the last one' didn't seem necessary.
Until people started cuing for the ATMs and the cue began to mis with the people waiting for the cashier. Hmmmm.
People standing around asking what the other one was waiting for and what position they were in the line. Scary confusion for something that seems quite easy to manage. Perhaps it's just in the DNA.
