Pretty much where it's headed.
In any case, what you should do is :
1. Pick up a Quorn pasty from the aisles.
2. Go to her checkout.
3. Place it on the conveyor.
4. STAY at the end of conveyor until she has scanned it and is looking at you, wanting you to come forward and claim your purchase.
5. Walk stiffly to the end of the conveyor, staring wide-eyed at her the whole time. ONLY move your head as you pass her, keeping your eyes locked.
6. With your right fist, SMASH THE PASTY.
7. IMMEDIATELY POINT AT HER.
8. Utter, "Do you KNOW what this MEANS!?!?". Tilt your head back at the end, keeping eye contact the whole time.
9. ??????
10. PROFIT.
