I think its ok to ask for ppl to pay for there own meals but it depends on the situation where its at and how its done
EG i would ask ppl if they could pay for there food if it was at a simple cheaper place ,we may have to do this at ours as we simply can not afford to cater for everyone if we want to get married.
But i would never ask ppl to pay for food if it was a set price or an expensive place
plus i think the way she said it is not tactfull at all, very ride and i would feel the same way u feel
