With the current economic climate will they be charging for the Free stuff??
I think if you go to a booth and you are seriously interested in those items, you can get samples.
What I find funny is watching people who never heard of the stuff come up to a table and try and shove as many samples as they can into their bag.
Vendors are there to show interested people their new products, existing items and more. Yes, try some samples, and take one if you want it, but when I worked a booth, I was amazed at some people.
A half hour before closing time, one guy came up to me, and started putting packets of stuff into his bag. I go, what are you doing, take ONE... and he actually said.. ah your closing, I am trying to help you so you don't have to take the samples back with you.
Certain products are not for certain people.
