You talking to me?

Today as I was getting to the ATM to transfer the payment of some bills I had almost forgotten I happened to have quite a bit of luggage with me since I had bought some stuff for the home on my way back from work. I've payed bills like this a thousand times now and as my hands were full, I inserted my cash card into the machine and as I realized that my hands were a bit too full to operate the machine, I put one of my bags on top of the machine.

A few seconds afterwards a voice from the machine that I interpreted as annoyed said "Don't put things on top of the machine" (ok, the annoyedness probably was mostly in my head, but still). If I only had had someone to argue with I would've told it to wait for one minute, but talking to the machine would probably just make me look crazy, so I took the bag down, put it on the floor and finished the transfer...

I love the convenience here in Japan with all the machines, but I feel that when they're getting uppity with you it has gone a little too far...
