Compliments

Do you ever compliment someone who does you a service? Or do you just accept that if they do their job in a friendly and helpful manner, that's what should happen and you would only comment if you didn't receive good service.
I received 2 written compliments yesterday. I don't know what I did differently from other days - it must have been that my clients were themselves happy and were sufficiently moved to write it down. It wasn't that I had a good night sleep (not likely given the hot weather in Melbourne).
Given that libraries have had a bit of bad publicity lately ( see theTelegraph, UK and News.com.au articles, I was very moved to receive some positive, written comments. It makes all the other times worthwhile.
So thanks to those lovely people for positive day.
But....
I do have to ask you to pay fines and charges and I do have to kick you off the computer if your behaviour is bad. And I do have to ask you to take your phone conversation outside if you annoy someone.
That's also part of my job!
