Have you ever been to a business show?

We've been invited and given a stand.
Now I don't really know what to expect.
I know what my company is offering but these are corporate companies and my boss said she doesn't want to do corporate events.
But perhaps headshots and team ones for LinkedIn!
I feel like a lemon whenever I go to these things, we do have booklets or any kind of price listings so I'm just talking abd redirecting people to her.
