Okay, two situations, Okay!
When I was a Pledge of a Fraternity, they had a House Mom as ALL Greeks did. Required. She did the cooking, light breakfest, cold cuts for lunch and Full blown dinner at evening meal. All Members who lived in the house ate there along with students living off campus and in dorms, there was no central School food service. Meals were M-F unless a party was planned with food. She got room and board with a little pay for her to do with what ever. Members of the Chapter were bus boys and dish washers to help defrey their costs. She taught many young men manners and decorum about dates, meeting people and dressing. I really loved her.
When I started the local, we broke the House Mother Rule, policed our selves and busted guts to show that we were just as good as the rest. Now, there are no house moms, and sometimes, I think it would be better to have one to keep everything on and in line.
Or three!
The LXA House at U Ks St.was previously a Soroity house, and a member of that Soroitys Father then was a LXA and a Bus Boy at the House. He received his meals for busing tables and cleaning dishes. When the Sority went off of campus, LXA bought it and he lived in it until graduation. This is on GC somewhere back when!
As I have said several times, a lot depends on the size of the School and Greek Organizations.
Presently, all of the Soroities at a my Alma Mater use a caterer for dinner meals only. They have to be competitive with the College food service to get the business.
Another point is, just how close the House is to campus, for the food part!
