What happens if I attend the Gourmet Dinner but skip out on the sales presentation lecture?

Unethical, perhaps.

But I get such things in the mail all the time. Some delicious full-course dinner at some fancy restaurant that most attend only a time or two in a lifetime.

The catch is, you commit to attend a lecture about flipping houses or investing in some pyramid scheme. Such presentations can run from an hour to several hours, and usually run over, enough that it spoils your dinner and you wonder why you ever agreed to it.

So, why not just say you have diarreah and have to call it a night? Or save yourself some embarrassment and just leave with no explanation (after eating of course). ?
