Dear Mary: Must we tip other people’s servants in London, too?

Q. What is the etiquette on tipping in London houses? I have been in the habit of staying with friends who don’t have cleaners and live fairly dishevelled lives so the question hasn’t come up before. But the other night my husband and I stayed for the first time with someone new. In the morning when we offered to strip the bed we were told she had someone coming in to do it. As we drove away it suddenly occurred to me that I should have left a tenner, but my husband says you only leave tips in the country as London dailies are overpaid and don’t have the same loyalty as country dailies. Please clarify.

A. Correctly brought up people leave tips in London as well and are wary of stripping beds without permission. It is not necessarily helpful to your host for a number of reasons to do with recycling of pillows that have not been slept on, or even of sheets if, for example, only a child has slept in the bed and the next incumbent will be a savage male youth.
