So I'm at the check-out and Mr. Cashier starts chatting.
Mr. Cashier: "Dude, you can't send these Danimals to school with your kids. They need to be refrigerated".
Dr. Grumpy: "My kids have them at home for snacks."
Mr. Cashier: "Good. They need to be refrigerated, ya know."
Dr. Grumpy: (getting out my wallet) "I'll put this on my debit card."
Mr. Cashier: "Okay. Maybe, instead, you should get snacks that don't need to be refrigerated, and that way your kids could have them at home or school".
Dr. Grumpy: (frantically trying to get out of there) "I'll just bag these myself, don't worry about it"
Mr. Cashier: "Or you could make your own protein shakes for kids, like with Ensure or ice cream or Slim-Fast? Or you could buy protein powder at health food stores? Or... Hey, you want your receipt? Where you going, Mister?"
