Chain Store Club Cards
The only thing I don't love about book stores is the pushy cashiers with thier book store club cards. No polite decline is acceptable, they just push with date rapist tenacity, "Let me tell you about the card. You know you want it. Take the card. You'll love it, just sign up. Your mouth says "no" but your eyes say "Sign me up for a discount card"
It's not the card itself, it's anything that's pushed on me with such enthusiasm, my knee-jerk reaction is to reject it. Plus it's not just "sure, ok" It's slow down the line while you fill out a form and everyone behind you gives you hateful dagger eyes the whole time.
Damn them! Damn their pushy discount cards!
