The GeekWithA.45 talks about his run in with Best Buy:

<blockquote>Here's a rough transcript of my interaction with the cashier &#38; subsequent managers:

<p>Chipper Teenage Cashier Girl: "May I have your phone number?"</p>

<p>This is common enough at a lot of places. Retailers want keys to link together purchases, and can mine a lot of information on buying trends and purchase patterns if they can define a household in a granular manner. This is also the purpose behind most grocery store discount cards. For the most part, this is a fairly benign activity, requiring the voluntary cooperation of the consumer. It's also an activity that I routinely decline to participate in.</p>

<p>Me {out of long habit}: "Nope. I don't give that out."</p>

<p><span class="caps">CTCG</span>: "Uh...the cash register says I have to get your address for this product."</p>

<p>Me: {knowing that satellite radio needs a subscription, and thinking this would set me up on the spot} Ok, That's G-e-e-k W-i-t-h...uh, this signs me for the subscription, right?</p>

<p><span class="caps">CTCG</span>: "Uh, no, it's just for our records..."</p>

<p>Me: {a slight frost creeping into my voice} "Then you don't need it."</blockquote></p>

<p>Hmm.. here is an easier method. Find the phone number for Best Buy. Give them that one. Works great, and has the added benifit of messing with their systems.</p>

<p>The poor, undertrained teenyboppers that work at these places do not make the rules - so just give them what they think they need and move on. :)</p>
