You should be wary of serving someone who can easily rattle off the ID number on their card, and make sure that the ID is valid.
While it does not necessarily imply anything suspicious, ID numbers are so long and random that the vast majority of people never bother to memorize them. So, you should always be suspicious of anyone who can remember details on their ID a little too well. Chances are he or she studied them beforehand.
