As the hot weather makes everyone a bit weird what has been your weirdest interaction in June?

I was waiting for the checkout at B&Q yesterday, the lady in front of me had a trolly packed with very large plant pots. Woman: I'd like to return these for a refund. Cashier: Ok, do you have your receipt? Woman: No. Cashier: We need a receipt so we know how much to refund. Woman: I paid £120. Cashier: We need a receipt to prove they were bought from this store in order to refund you. Woman: Well, I don't have a receipt... Cashier: You didn't get a receipt or you've lost the receipt? Woman: I didn't get a receipt. Cashier: You always get a receipt when you buy something here.... Woman: I didn't buy them here, they were out of stock. Cashier: You didn't buy them here? Where did you buy them? Woman: Online. They were out of stock here. Cashier: We can only refund items that were bought from the store. If you bought them on our website there's a returns process where they'll collect... Woman (getting angry): I couldn't buy them here because they were out of stock! Cashier: I can only refund items if you have a receipt... Woman: I told you I don't have a receipt! Cashier (getting increasing bewildered): You'll have to go to the website... Woman: What website? Cashier: they one you bought the plant pots from.. Woman: which one? Cashier (very confused): what? you... did you buy these plant pots from the B&Q website? Woman: B&Q were out of stock! I keep telling you! Cashier: I don't think I can help you... Woman: Well, what am I supposed to do?!
