Dilbert is at the checkout line of a supermarket. The cashier asks him, "Are you a member of our frequent grocery club?" Dilbert responds, "No, what is it?" The cashier replies, "You get a membership card that entitles you to discounts." Dilbert says, "Let's see if I have this straight..." Dilbert continues, "I'll be inconvenienced by having to fill out a form and carry your stupid card around..." Dilbert continues, "And in return, you'll put me on a junk mail list, and charge me the same as the grocery store across the street?" Dilbert yells, "AND YOU EXPECT ME TO BE HAPPY ABOUT IT?!!" The customer in line behind Dilbert says, "But it's free!" The cashier says into the intercom, "Cleanup on register two.. it's engineer spittle."
