The presenters and agents do know you are the shoper as soon as you decline the gift card. The insurance company doesn't mind because the fact that the presenter knows that a shopper is observing and reporting on the seminar keeps them in compliance with strict Medicare rules, regs, and laws. They don't dare deviate from the CMS requirements.
I am doing 41 shops for the same insurance company this month alone. That video sure does get old! But each presentation can be a little bit different so you have to keep your ears tuned in when the speaker talks.
Love October and November for these shops! I just plop myself down at the same restaurant for two or three presentations a day. Have laptop, will compose reports during the breaks. Easy!
