Of course, we could substitute a beer or two in Atlanta. I know that when I worked in dining services, while I had a right of first refusal, in over 10 years, I never used it once. Why, because in most cases, the contract didn't really give me that option. In most cases, my contract for the summer months was written differently than for the school year. In order to keep the dining halls open, I pasted on more of the expenses to the administration.
Some contracts work on a fee basis during the summer.
You pay for the services plus a fee to the Company. Also, keep in mind, that many times dining services does have staff around during the summer. I would be surprised if you couldn't fine a local catering operation that would love to come on campus to provide you with meals. He, is right, know your contract. Also, use your resources like some of us to help.
