When Francine comes back into the Wingman bar after the van ride with MacGyver, she's somehow had time to get her hair done. It's curlier and fuller than in the previous scenes, which would have been minutes before.
Sparky impatiently says that he doesn't know how to spell Mr. Jastrow's last name, yet the agent's name and phone number are written on the letter that Francine left for Sparky, and the letter is right there on the counter in front of him; he could just look at it again to find the spelling. As vitally important as the phone call to the Justice Department was to Francine, Sparky would be unlikely to antagonize the authorities by being any more "difficult" toward them than he needed to be.
