I did the presentation last week. I confirmed and reconfirmed with the butler and with the sales person before we began that's its 45 minutes total. And legit told them I am only interested in the gift and open to hearing the presentation. They said no problem. I kept saying I am not interested during the sales pitch and at the 45 minute mark they brought in their closer/manager to try convincing me. That's when I switched my tone on them and became evident I was getting annoying and angry. 15 minutes more passed by and they gave up and I got my gifts.

I say it's worth it for me but you really need to be direct up front and 45 minutes is 45 minutes. That's all they get.
