Just a Little Something - Mystery Purchases

This muffles screams pretty well, right? I mean... Image via Wikipedia

Every time I go to the hardware store I think about all the deadly weapons they sell and if there are certain "red flag" product combinations that cashiers have to watch out for. If I buy a hatchet and bleach, does my name go on a list somewhere? What if I add rope and large plastic bags?

Try this fun scenario:
Go buy some garden shears, a chainsaw, duct tape, bungee chords, trash bags, shop towels and some red paint. Pay in all cash and stare blankly at the cashier. No smile. No conversation.

After you leave the cashier will run through several murderous fantasies in his/her mind, wondering if they should genuinely be concerned. The red paint, however, will confuse them and ultimately diffuse suspicion.

Then later, after he/she has had enough time to forget about you, come back covered in red and purchase a shovel.
