Argh, I hate this sort of thing.
We use an agency, but always have the same girl and she's lovely. We've even met her family and they're all lovely. I don't know her well enough to call her a friend, but we are fond of her. I hadn't got her a Christmas present, and it seems they struggle on a low wage, so I didn't know what to do.
So I put £10 in a Christmas card because that was all I could afford at the moment (and had on me) ? I wrote a nice thank you note inside the card too, saying how much we appreciate her help.
So do you tip? And is £10 embarrassingly little? ? I have no idea what she's paid, but I pay the agency £9 per hour.
