Finally , I called the United reservations number and reported the Dulles domestic check - in problem . The representative placed me on hold and checked with IAD operations . She came back on line and told me that there was a shortage of employees that day . I was very satisfied with that answer , though this did n't excuse United management 's responsibility to at least direct passengers , employees , and contractors to keep the lines moving .
Why would I be satisfied with the reason for my trouble with United ?
- I am glad because I was able to speak with an old friend at customer service .
 - The reason given is logical and explanatory .
 - None of the above choices .
 - I am glad because they gave me a full refund .


The reason given is logical and explanatory .
