I'm suggesting the Rant Line ... And as an example, and possibly the first entry, I humbly offer my rant.
You are in a line at a shop... The person in front is waiting, merchandise in hand possibly ... They arrive at the counter to be served, the attendant sorts and totals and says that will be X dollars.
Then, and only then does the customer start digging in their bag for their money!
This pees me off no end ... Why the bleeding hell can't they use the time spent waiting to be prepared?
End of Rant ... You can all move on now.
