<td>Customer holding this record</td>
<td>owner</td>
<td>8</td>
<td>The id value (an 8 digit number) of the customer who has booked this.
Note that for this application,
you should assume that customers and CSRs
know their customer ids. The system you are writing does not interact with
these numbers, rather it simply records them. If this field is all blanks, the
record is available for sale.</td>
OK - but what 8 digit to use? IP?
