I wonder how they draw that conclusion. I mean, if it's just a suspicious address that it was coming from I would have thought that they would x-ray the package before confronting you.
I would feel like they are crossing the line by coming to my place of business with this sort of thing. A person could get into a lot of trouble with their boss because of the DEA's mistake.
Send me your address and I will send ya some baking soda and we can see what happens!
BTW, congrats on your new cue. How about some pictures of it?
Ill bet they had a dog sniff it. If not they should have.
