Good evening Stuart,
Just in reply to your comment about the aisles getting smaller in department stores such as Kmart, I generally try to avoid the department stores where they have a whole heap of checkouts at the front of the store as I end up spending much more time in the queue that I spend in the rest of the store. I much prefer the stores such as Myer and David Jones where each department has its own checkout.
If I have to use the stores with checkouts at the front then I will usually try to use the "entertainment" checkout towards the rear of the store so that I can walk straight out, or favour the stores that have introduced self-serve checkouts, such as Big W.
Actually I think the self-serve checkouts are a great idea as they generally take over some space which was previously used by the fifteen or so checkouts that were never open anyway. I was never able to understand why the department stores would have roughly twenty checkouts, and only ever use five of them.
P.S. If you see Glenn Wheeler before tomorrow afternoon, remind him to take a parachute!
