Thinking of having a birthday lunch for DH's 40 th next year at a local restaurant. Want to invite 30-40 family and friends including kids. They have a set lunch menu for about £15 pp. Would people expect us to pay for them if we invite them? If we were inviting them to a house party or an evening do in a hall, we wouldn't expect them to cough up for food and drink so should I be paying for them for lunch? It's just we can't afford to pay for everyone and our house isn't big enough to host everyone either and we want it to be a day thing. What's the etiquette on this.
many thanks
