This browser dialog was produced as part of the flow of stopping gas service. The text and buttons combine for almost perfect ambiguity. Continue to stop the service? Continue the service? Cancel stopping the service or Cancel the service?
You have elected to stop your NSTAR service. Do you wish to continue?
Much clearer would be text and button labels such as:
You have elected to stop your NSTAR service. Please confirm that choice:
Yes - please stop my service
No - I have changed my mind
Even a simple yes / no would be so much better.
