I used to sort of start as I mean to go on. I had a lovely friend of nearly 80 years old when I was coming up to 40 ish. So we often had a day in the week when I would take her somewhere in the car and we would go for a walk near a river or in the dales and then have something to eat. As I had a family I was going home to cook a main meal for three so was only thinking of a sandwich or maybe soup on a cold day. she was a widow and of course did not make full roast dinners for herself and had said how she missed that sort of meal. She had enjoyed having dinner with us sometimes . so I said to her look we will buy our own food and if we want we can sometimes buy each other a coffee earlier or later, because I dont need a main meal at lunchtime and I am sure you would prefer to have that roast rather than a sandwich etc. She agreed and it worked out well. we just had what we wanted and paid for our own which gave us free reign to do as we pleased and enjoy our lunch whatever it was Sometimes she would have a roast, but in the winter we actually often had similar lunches as we both liked good jacket potatoes with a filling , but the whole point was to sort it out in the beginning and be open and then it is easy. So if it was an occasion I could say I am buying your birthday lunch today and we shall go to that cafe we like etc. Now I am the widow living alone and it is the opposite way. I am a singer and we rehearse on sundays with one choir so do not eat lot before singing, but rather sad that lots of places do sunday lunch or carvery and it is not sensible for me to have them but occasionally I have done that as a treat. Gone very early so plenty of time before I start to sing. Lovely to have a roast or carvery, good choice of everything , no washing up, a treat for me. I do in general prefer to make some sort of arrangement with people before you get to the restaurant so that you all know where you stand , so sometimes we might pay for our own, or in a good chinese restaurant where we love all the dimsum we all put so much in a kitty so that we can try lots of bits and pieces. When I am having a sticky patch with bills, I will just say I could meet you for coffee afterwards but cant do the cafe this week. Or sometimes have suggested that they come to my house for coffee and biscuits after or whatever. the first time it can feel a bit embarrasing for some people to talk like this but it is so worth while. You all know how things stand, sort your own idea out and then this awful creeping resentment or feeling that you cant say anything to someone can ruin a friendship. My friends are precious to me , male or female, and I would be very sorry to gradually drift away from someone important to me just over bills . I do not want to be patronised , or be the poor relation where they always pay, but by being honest in the beginning we work it out. I might add that I keep a plates and cutlery and kitchen roll with me if I go out and have had many take away chinese or whatever under the stars up on the wolds at a much cheaper price than going into a restaurant and waiting about. I can look out at a lovely view or listen to radio 3 and am very happy doing that. Perhaps a night time picnic might work as you could buythe food and bring your own drink if you are not driving ??
