When I am done making a purchase, the machine always 'asks' politely whether it may help me further. I may be weird, but in my mind, I always think 'no, thank you'. The options are, of course, 'yes' or 'no'.
Which makes me wonder if more automated machines used standard polite options, would people start to pick them up? Granted, it's probably not going to change the world, but a little more politeness in the world can't be a bad thing.
That is all. Thank you for taking the time to read my thoughts.
