I have the following LINQ expression that's not returning the appropriate response

    var query = from quote in db.Quotes
                where quote.QuoteStatus == "Estimating" || quote.QuoteStatus == "Rejected"
                from emp in db.Employees
                where emp.EmployeeID == quote.EmployeeID
                orderby quote.QuoteID descending
                select new 
                { 
                    quote.QuoteID, 
                    quote.DateDue, 
                    Company = quote.Company.CompanyName, 
                    Attachments = quote.Attachments.Count, 
                    Employee = emp.FullName, 
                    Estimator = 
                       (quote.EstimatorID != null 
                       && quote.EstimatorID != String.Empty) 
                          ? db.Employees.Single
                              (c => c.EmployeeID == quote.EstimatorID).FullName 
                          : "Unassigned", 
                    Status = quote.QuoteStatus, Priority = quote.Priority 
                };

The problem lies in the Estimator = (quote.EstimatorID != null && quote.EstimatorID != String.Empty) ? db.Employees.Single(c => c.EmployeeID == quote.EstimatorID).FullName : "Unassigned" part.

I NEVER get it to evalueate to "Unassigned", on the ones that are supposed to, it just returns null. Have I written this wrong?
