Assumption makes an ass out of the waitress.

My friend Kate went for dinner recently with some friends at a restaurant. After sorting out who was paying what, Kate paid and left the change for her friend in her vacant seat as her friend had gone to use the toilet. When the waitress arrived with the order she started picking up the change, assuming it was a tip for herself for doing such a damn fine job of bringing the plates over. After collecting the majority of pennies she looked up to see the whole table looking at her in shared confusion. ”Oh, is this not for me?” she asked. ”No, it’s my friend’s change” replied Kate. The waitress went bright red and disappeared into the kitchen.
