I started dipping before the age of 18 as I'm sure many of you have.
  Although I did not have too many problems buying dip, I did run into the
occasional clerk on a power trip. One fool proof method I developed for
 buying dip when I was underage was this:

1. Walk into the store talking on your
cell phone (no one needs to be on the other end).

2. While looking at things infornt of the
counter casually mention to the "person"
 on the phone that you are transfering
 from one college to another (mention
the names of popular local schools, and
make sure the clerk is within ear shot)

3. Then, say "hey hold on I need to get
  a can of dip" to the person on the phone
 
4. Casually ask the clerk for a can of dip.

This method has worked, not only for
 me, but many of my buddys.  It never
 failed me. Try it out and let me know
how it worked.
