I then went over to clear a table near him, and he said
'So Olga, are you always this happy?'
To which I replied 'Um, kind of, I guess. And I have a pretty good customer service smile for when I'm not!'
And then he basically said that it looked like I was cheerful and enjoying myself and happy about being where I was, and that was a really lovely thing. And he said I 'radiated joy'. (Hmm, sounds a little creepy now that I'm typing it, but it wasn't at all.)
Anyway, I'm not sure if it's relevant, but he was Australian, and he said that quite a lot of the people working in things like retail and hospitality over here can tend to be quite rude. I guess it goes both ways, sometimes hospitality workers can be rude and unpleasant, and sometimes customers can be even ruder and more unpleasant. And then one of these bunches of people makes life hell for the other bunch, until everyone is stupid and pointlessly mean.
So it is quite a lovely surprise when people are not awful - when customers not only realise that you're a human person, but also say nice things to you, and about you.
Also, it's nice to remember that although my job is not an especially important one, I am pretty good at it, and not everyone is.
Then there was another customer who looked at my name badge and started speaking to me in Polish. As you do.
