Caller asked for (first and last name) of unknown person.  Then asked for (last name) of former employee.  Both times I said "that name is not on the roster."  Then the caller said, "Maybe you can help me.  I'm looking for the person in charge of food and drink there...vending services."  When asked, she provided me with her first name and last initial, calling from Accent Food Services.  She gave me the address, call back number, and web site address.  I told her I would pass the information along, thanked her for calling, wished her a nice day and ended the call.
