My veggie friend visits me and i try to buy them special food but they are never happy, what do i do? ?

i try to buy veggie stuff for them, but they say they dont like quorn, they dont want too much soya as they think there is too much "estrogen" in it, so i get wheat based products but they complain they dont like meat substitutes, they wont eat free range eggs when i get them though they eat omelettes when they are out, they say they dont like getting "take aways" either indian, chinese, or chip shops or anything because they think they are too much of a pain to put on a plate (??), and now when i tried to take them out to lunch today they said there was nothing suitable and there was nothing in this city to eat for a vegetarian, though it is one of the most international city in the uk and you can get anything. if i dont suggest anything THEN they say i dont feed them! i took them to marks and spencers where they have risottos, pasta, quiches, potatoes, EVERYTHING and they didnt want that either. WHAT DO I DO WITH THEM?? say they are old enough to feed themselves and if they get hungry enough they will eat? i feel like im dealing with a toddler. :/
