A while ago I wrote about how I thought it was a shame that so many places seem to be opting for the use of self-service machines. Today, I found myself on the opposite of the bench - I had waited for over ten minutes to post my items and when I handed them she pointed out that I had done something slightly wrong with the parcels. Instead of offering to help she spoke to me as if I was a total idiot for making that mistake and implied that I was wasting her time. Thankfully I had a friend with me who helped me sort it out but after that I chose to use the machine to pay to send it - there was no queue and I knew it couldn't upset me or be rude. I will say that one of the people on the other tills was lovely and very helpful when I wasn't sure what to do with the package as it wouldn't fit in the slot by the machines.
Overall, I will say I still prefer being served by live people rather than me having to navigate lots of buttons on a screen; but I also think that it wouldn't kill people to simply polite rather than assume that everyone who isn't them is stupid and/or wasting their time.
