Q. When my husband and I meet certain friends for lunch, the bill is always higher than it should be, since one friend orders about five different dishes because she’s never sure what she wants. She barely touches any of them. We don’t want to quibble when it comes to dividing the bill, but we have retired and have to be watchful of our spending, unlike them. What should we do?

A. Next time, you and your husband could feign reduced appetites due to a hectic social life and order small starters for each course. Then, when your friend doesn’t eat the array of dishes presented, you can help yourselves without guilt, claiming it looks too delicious not to eat. ‘Mmm – we were hungrier than we thought!’

Q. I am doing a postgraduate degree in a European university. I want to go into publishing and applied for a subediting job on a well-regarded literary magazine here (I am bilingual). I was interviewed and appointed and duly posted on Instagram. Now I find it is unpaid, though this was never mentioned to me. I believe it was known that I could afford to do it pro bono, which is true, but now I feel slightly ‘played’. How should I extricate myself?

A. Turn a blind eye to the possible reasons for your appointment and do the job. Whether you were played or not, you should not let personal pride come between you and a valuable learning experience.

Q. I have just moved to London from Seville and was happy when a neighbour invited me for drinks. She said ‘Come any time, but not too early’, so I came at 8 p.m., but she said she had assumed I was not coming and was about to go out. How could I have made things right?

A. Unlike in Spain, drinks in England take place between 6 and 8 p.m. You could have immediately invited her to drinks with you at 6 p.m. the following night. This would have shown sufficient enthusiasm on your part to dispel any bitterness from the neighbour (who was at fault for not specifying a time).

Q. Re your correspondent of 18 March, surprisingly few good hotels in Paris have single beds. This same situation arose for me some years ago, and when I remarked to the glamorous receptionist ‘So I have to sleep with another man’, she remarked without humour: ‘It has been known.’ Our friendship survived.

A. Thank you for shedding further light on this dilemma. You are right, and indeed even twin beds in Paris are usually pushed very close together, putting one of the roommates into the awkward position of having to push them apart.
