I infer from your post that you are also OK with getting 15 of the same free sample (or 30 for that matter) at the grocery store, because “hey its free, and I’m just being smart”.
You remind me of that Family Guy episode when Peter kept coming around to the sample booth with disguises so he could keep eating more. That is until the guy running the booth told him to quit bothering with disguises, he can have all he wants anyway.
