To add one more variable to this, Disney hires a wide variety of employees, including special needs. If the training says they are to take the card, do A, punch B, remove the receipt, give receipt to customer, changing this can really disrupt them. I'm not saying this is the situation, just saying you never know. I use a local Taco Bell frequently, and they always ask if I want my receipt. I say no. But I know there is 1 cashier that will still hand it to me. It is very simple to just take it and put it in the trash.
