(A customer comes up with a 40 pound tree teetering on the edge of her flatbed cart.)

Customer: “This tree sure is wobbly!”

Me: “Just be careful with it, ma’am. Don’t let it fall.”

(As I lean down to scan several other smaller plants, the customer lets go of the tree and it hits me on the head.)

Me: “Ouch!”

Customer: “You should improve your attitude. You haven’t smiled once this whole time!”
