Does anyone charge for client seminars and/or on-site meetings that are beneficial to YOUR business?
I recently went to a networking meeting with my client. She wanted to introduce me to her collegues, and to see if I was interested in joining, etc. I did not charge for that because I was asked five times for a business card. I learned from it, and found it beneficial to MY business.
She now wants me to attend one of her seminars so I can learn her business, and possibly network. (She's a networking junkie!

) I am stuck on when to charge for these types of things and when not to.
Does anyone have local clients and run into the same situation?
Thanks much!
